Patients with unstable angina or non-ST-segment elevation myocardial infarction (NSTEMI) can be cared for with a routine invasive strategy involving coronary angiography and revascularization or more conservatively with a selective invasive strategy in which only those with recurrent or inducible ischemia are referred for acute intervention.
242. Effects of antibiotic therapy on outcomes of patients with coronary artery disease: a meta-analysis of randomized controlled trials.
Although Chlamydia pneumoniae infection has been associated with the initiation and progression of atherosclerosis, results of clinical trials investigating antichlamydial antibiotics as adjuncts to standard therapy in patients with coronary artery disease (CAD) have been inconsistent.
243. Personal use of hair dyes and risk of cancer: a meta-analysis.
Use of hair dyes has been suggested recently as a risk factor for several types of cancer in epidemiologic studies. This alarming news and controversial declarations by scientific organizations and general media have made necessary a systematic evaluation of the epidemiologic evidence.
244. Behavior problems and mental health referrals of international adoptees: a meta-analysis.
International adoption involves more than 40,000 children a year moving among more than 100 countries. Before adoption, international adoptees often experience insufficient medical care, malnutrition, maternal separation, and neglect and abuse in orphanages.

The role and dose of oral vitamin D supplementation in nonvertebral fracture prevention have not been well established.
246. Clinical validity of a negative computed tomography scan in patients with suspected pulmonary embolism: a systematic review.
作者: Rene Quiroz.;Nils Kucher.;Kelly H Zou.;Florian Kipfmueller.;Philip Costello.;Samuel Z Goldhaber.;U Joseph Schoepf.
来源: JAMA. 2005年293卷16期2012-7页
The clinical validity of using computed tomography (CT) to diagnose peripheral pulmonary embolism is uncertain. Insufficient sensitivity for peripheral pulmonary embolism is considered the principal limitation of CT.
247. Short-term risk of death after treatment with nesiritide for decompensated heart failure: a pooled analysis of randomized controlled trials.
作者: Jonathan D Sackner-Bernstein.;Marcin Kowalski.;Marshal Fox.;Keith Aaronson.
来源: JAMA. 2005年293卷15期1900-5页
Nesiritide improves symptoms in patients with acutely decompensated heart failure compared with placebo and appears to be safer than dobutamine. Its short-term safety relative to standard diuretic and vasodilator therapies is less clear.
248. Abciximab as adjunctive therapy to reperfusion in acute ST-segment elevation myocardial infarction: a meta-analysis of randomized trials.
作者: Giuseppe De Luca.;Harry Suryapranata.;Gregg W Stone.;David Antoniucci.;James E Tcheng.;Franz-Josef Neumann.;Frans Van de Werf.;Elliott M Antman.;Eric J Topol.
来源: JAMA. 2005年293卷14期1759-65页
The benefits of abciximab in patients with ST-segment elevation myocardial infarction (STEMI) are still a matter of debate.
249. Association between compensation status and outcome after surgery: a meta-analysis.
作者: Ian Harris.;Jonathan Mulford.;Michael Solomon.;James M van Gelder.;Jane Young.
来源: JAMA. 2005年293卷13期1644-52页
Compensation, whether through workers' compensation or through litigation, has been associated with poor outcome after surgery; however, this association has not been examined by meta-analysis.
250. Evaluation of new treatments in radiation oncology: are they better than standard treatments?
作者: Heloisa P Soares.;Ambuj Kumar.;Stephanie Daniels.;Suzanne Swann.;Alan Cantor.;Iztok Hozo.;Mike Clark.;Fadila Serdarevic.;Clement Gwede.;Andy Trotti.;Benjamin Djulbegovic.
来源: JAMA. 2005年293卷8期970-8页
The superiority of innovative over standard treatments is not known. To describe accurately the outcomes of innovations that are tested in randomized controlled trials (RCTs) 3 factors have to be considered: publication rate, quality of trials, and the choice of the adequate comparator intervention.
251. Implantable defibrillators for the prevention of mortality in patients with nonischemic cardiomyopathy: a meta-analysis of randomized controlled trials.
作者: Akshay S Desai.;James C Fang.;William H Maisel.;Kenneth L Baughman.
来源: JAMA. 2004年292卷23期2874-9页
Implantable cardioverter defibrillator (ICD) therapy is effective in primary and secondary prevention of sudden cardiac death among patients with prior myocardial infarction and depressed ejection fraction. However, conclusive evidence of survival benefit in patients with nonischemic cardiomyopathy (NICM) is still lacking.
252. Trends in the risks and benefits to patients with cancer participating in phase 1 clinical trials.
作者: Thomas G Roberts.;Bernardo H Goulart.;Lee Squitieri.;Sarah C Stallings.;Elkan F Halpern.;Bruce A Chabner.;G Scott Gazelle.;Stan N Finkelstein.;Jeffrey W Clark.
来源: JAMA. 2004年292卷17期2130-40页
In the past, cancer patients entering phase 1 studies confronted the prospects of high risk and unlikely benefit. Over the last decade, cancer drugs under development have become more targeted, and the clinical research environment has become more scrutinized. The impact of these changes on the risks and benefits to patients who participate in phase 1 cancer trials is unknown.
253. Bariatric surgery: a systematic review and meta-analysis.

About 5% of the US population is morbidly obese. This disease remains largely refractory to diet and drug therapy, but generally responds well to bariatric surgery.
254. Benefits of adding a drug to a single-agent or a 2-agent chemotherapy regimen in advanced non-small-cell lung cancer: a meta-analysis.
作者: Catherine Delbaldo.;Stefan Michiels.;Nathalie Syz.;Jean-Charles Soria.;Thierry Le Chevalier.;Jean-Pierre Pignon.
来源: JAMA. 2004年292卷4期470-84页
Randomized trials have demonstrated that adding a drug to a single-agent or to a 2-agent regimen increased the tumor response rate in patients with advanced non-small-cell lung cancer (NSCLC), although its impact on survival remains controversial.
255. Pharmacological management to reduce exacerbations in adults with asthma: a systematic review and meta-analysis.
Over the last 2 decades, many new pharmacological agents have been introduced to reduce the growing morbidity associated with asthma, but the long-term effects of these agents on exacerbations are unclear.

作者: Gilles Montalescot.;Maria Borentain.;Laurent Payot.;Jean Philippe Collet.;Daniel Thomas.
来源: JAMA. 2004年292卷3期362-6页
Glycoprotein IIb/IIIa (Gp IIb/IIIa) inhibitors improve myocardial reperfusion and clinical outcomes of patients undergoing primary percutaneous coronary intervention (PCI), but optimal timing of administration remains unclear. No systematic reviews have comprehensively examined the effects of early vs delayed administration of these agents.
257. Highly active antiretroviral therapy and sexual risk behavior: a meta-analytic review.
Evidence suggests that since highly active antiretroviral therapy (HAART) became available, the prevalence of unprotected sex and the incidence of sexually transmitted infections (STIs) have increased.
259. Drug treatment of hyperlipidemia in women.
Several clinical trials have evaluated the effects of lipid-lowering medications on coronary heart disease (CHD). Many of the trials have not included enough women to allow sex-specific analyses or have not reported results in women separately.
260. Effect of Vitamin D on falls: a meta-analysis.
作者: Heike A Bischoff-Ferrari.;Bess Dawson-Hughes.;Walter C Willett.;Hannes B Staehelin.;Marlet G Bazemore.;Robert Y Zee.;John B Wong.
