383. Full publication of results initially presented in abstracts. A meta-analysis.
To estimate the rate of full publication of the results of randomized clinical trials initially presented as abstracts at national ophthalmology meetings in 1988 and 1989; and to combine data from this study with data from similar studies to determine the rate at which abstracts are subsequently published in full and the association between selected study characteristics and full publication.
385. A meta-analysis of methods to prevent venous thromboembolism following total hip replacement.
While several methods of prophylaxis have been shown to reduce the risk of venous thromboembolism following total hip replacement, the safest and most effective agent is unclear. To clarify this issue, we performed a meta-analysis of the randomized trials of methods used to prevent venous thromboembolism following total hip replacement.
387. Patient outcomes following tricompartmental total knee replacement. A meta-analysis.
To provide estimates of patient outcomes following tricompartmental knee replacement and to examine variation in outcomes due to patient and prosthesis characteristics.
388. Efficacy of BCG vaccine in the prevention of tuberculosis. Meta-analysis of the published literature.
作者: G A Colditz.;T F Brewer.;C S Berkey.;M E Wilson.;E Burdick.;H V Fineberg.;F Mosteller.
来源: JAMA. 1994年271卷9期698-702页
To quantify the efficacy of BCG vaccine against tuberculosis (TB).
389. Female gender as a risk factor for torsades de pointes associated with cardiovascular drugs.
To test the hypothesis that female prevalence is greater than expected among reported cases of torsades de pointes associated with cardiovascular drugs that prolong cardiac repolarization.
390. The association between beta-agonist use and death from asthma. A meta-analytic integration of case-control studies.
The purpose of this investigation was to provide an empirical summary of the evidence regarding the association between beta-agonist use and death from asthma. This effort integrated the results of case-control studies that examined the use of beta-agonists among asthmatic patients who died and the use of beta-agonists among asthmatic patients who did not die. The possible moderating effects of patient sample age and mode of delivery (oral, metered-dose inhaler, and nebulizer) were also examined.
391. Use of antibiotics in preventing recurrent acute otitis media and in treating otitis media with effusion. A meta-analytic attempt to resolve the brouhaha.
作者: R L Williams.;T C Chalmers.;K C Stange.;F T Chalmers.;S J Bowlin.
来源: JAMA. 1993年270卷11期1344-51页
To determine the efficacy of antibiotics for prophylaxis of recurrent otitis media and treatment of otitis media with effusion (OME) in children.
394. A comparison of results of meta-analyses of randomized control trials and recommendations of clinical experts. Treatments for myocardial infarction.
To examine the temporal relationship between accumulating data from randomized control trials of treatments for myocardial infarction and the recommendations of clinical experts writing review articles and textbook chapters.
395. Comparison of different metronidazole therapeutic regimens for bacterial vaginosis. A meta-analysis.
To evaluate the treatment of bacterial vaginosis with metronidazole to determine if there is a therapeutic regimen that is superior to all others with regard to cure and recurrence rates.
396. Transparent polyurethane film as an intravenous catheter dressing. A meta-analysis of the infection risks.
To obtain a quantitative estimate of the impact on infectious complications of using transparent dressings with intravenous catheters.
397. An overview of interventions to improve compliance with appointment keeping for medical services.
To determine, by a quantitative meta-analysis of randomized trials, the effectiveness of strategies to improve patient compliance with screening, referral, and clinic appointments for health services that are provided at the time of the visit.
399. Intrathecal therapy in tetanus. A meta-analysis.
--To assess the efficacy of intrathecal therapy with tetanus antibody (antitetanus equine serum or human tetanus immune globulin) in neonatal and adult tetanus using meta-analytical techniques.
400. A meta-analysis of low-dose aspirin for the prevention of pregnancy-induced hypertensive disease.
--Pregnancy-induced hypertension (PIH), defined as either isolated hypertension after the 20th week of gestation or hypertension with proteinuria (preeclampsia), occurs in 5% to 15% of pregnancies and is associated with maternal and neonatal morbidity. Previous clinical trials with small numbers of patients have suggested that aspirin in doses of 60 to 150 mg/d during the second and third trimesters reduces the risk of PIH and improves maternal and neonatal outcomes.
