This paper is based on the answers of 400 test takers to the test. All participants earned a master degree either in humanities or science...

To date, many studies have been conducted to compare the performance of different DIF procedures using simulated data sets. However, some results from these simulation studies are inconsistent with one other (e.g., Hidalgo & López-Pina, 2004; Jodoin & Gierl, 2001). This study used real data to systematically investigate the consistencies of DIF detection and effect size among three widely-used ...

RESULTSdTwenty-eight trials enrolling 11,880 and 9,175 patients for DPP-4 inhibitors and comparators, respectively, were included, reporting 63 fractures. DPP-4 inhibitors, compared with placebo or other treatments, were associated with a reduced risk of fractures (Mantel– Haenszel odds ratio [MH-OR] 0.60, 95% CI 0.37–0.99, P = 0.045), even after the exclusion of comparisons with thiazolidinedi...

Methods. A comprehensive literature search was conducted to identify clinical trials that focused on the prevention of EA in children anaesthetized with sevoflurane, desflurane, or both. The data from each trial were combined using the Mantel–Haenszel model to calculate the pooled odds ratio (OR) and 95% confidence interval. I statistics were used to assess statistics heterogeneity and the funn...
