In mixed methods reviewing, data from quantitative and qualitative studies are combined at the review level. One possible way to combine findings of quantitative and qualitative studies is to quantitize qualitative findings prior to their i...
The median and the mode as robust meta-analysis estimators in the presence of small-study effects and outliers [0.03%]
小规模研究效应和异常值存在时中位数和众数作为稳健的元分析估计量的有效性研究

Daniël A Korevaar et al.
Introduction: Many diagnostic accuracy studies are never reported in full in a peer-reviewed journal. Searching for unpublished studies may avoid bias due to selective publication, enrich the power of systematic reviews, ...
A comparison of Bayesian and frequentist methods in random-effects network meta-analysis of binary data [0.03%]
贝叶斯方法与频率学派方法在二分类结局间接比较网络meta分析中的比较研究
