Meta-analysis that assessed the magnitude of behavior change produced by subliminal vs. supraliminal drive-related stimuli was performed on all subliminal psychodynamic activation (SPA) studies that employed both types of stimuli (N of studies = 11, N of subliminal-supraliminal comparisons = 43). The analysis revealed…

This review used quantitative and qualitative techniques to integrate the alcohol and aggression literature. The primary purpose of the review was to determine if a causal relation exists between alcohol and aggression. The main meta-analysis included 30 experimental studies that used between-subjects designs, male con…

In this correspondence, we raised our concerns about the methodological issues in the recent network meta-analysis by Yang et al. These issues require close attention because such meta-analysis forms the basis of major guidelines and helps clinicians make informed decisions.

If meta-analysis is to provide valuable answers, then it is critical to ensure clarity about the questions being asked. Here, we distinguish two important questions concerning cognitive bias modification research that are not differentiated in the meta-analysis recently published by Cristea(2015) in this journal: (1) d…

Point estimation for the selected treatment in a two-stage drop-the-loser trial is not straightforward because a substantial bias can be induced in the standard maximum likelihood estimate (MLE) through the first stage selection process. Research has generally focused on alternative estimation strategies that apply a b…

The orthopedic surgeon performing total hip arthroplasty (THA) today has many choices in the selection of the implant and mode of fixation. The clinical perspective, obtained from the available literature, is presented to facilitate these decisions by reviewing results of cemented and cementless primary and revision TH…

OBJECTIVES: This study was undertaken to determine whether exposure at work to environmental tobacco smoke is associated with an increased risk of lung cancer. METHODS: Data from 14 studies providing information on lung cancer and exposure to environmental tobacco smoke at work were examined. Six quality criteria were…

Evolutionary-related hypotheses about gender differences in mate selection preferences were derived from Triver's parental investment model, which contends that women are more likely than men to seek a mate who possesses nonphysical characteristics that maximize the survival or reproductive prospects of their offspring…

Since it will be some time until data will be available comparing clomipramine and fluoxetine for the treatment of patients with obsessive-compulsive disorder (OCD), a meta-analysis of previous studies was performed in an attempt to gain some information about comparable efficacy and side effects of these two commonly…

Meta-analysis of published series of intramedullary rod fixation in fractured femurs revealed significantly higher union rates, lower deep infection rates and a better range of knee motion when closed rather than open techniques of insertion were used. A separate retrospective review of 58 femoral fractures at one hosp…
