The power performance of test statistics are examined and compared via simulation studies and we find our approximate method is more effective to identifying outliers in meta-regression models. In addition, we propose a modified model to accommodate outliers in meta-regression model. Two examples are...
「meta 迴歸」程序會在效應大小與共變數之間建置線性迴歸模型。 目標或應變數會作為效應大小; 預測值是共變數,也稱為控管者,並記錄為研究層次 (例如,研究位置、研究測試環境及藥物管理方法)。 元迴歸的目標是探索並解釋研究之間的異質性 (個體研究的真實效應大小的差異) 作為主持人的函式。 II 型糖尿病藥物研究...

Recently, network meta-analysis of survival data with a multidimensional treatment effect was introduced. With these models the hazard ratio is not assumed to be constant over time, thereby reducing the possibility of violating transitivity in indirect c
The Meta Regression procedure builds linear regression models between the effect size and the covariate. The target or the dependent variable serves as the effect size; the predictors are the covariates, which are also called moderators and recorded as the study level (for example, the study locat...

The value of the Cochran statistic is the same for all multilevel models with the same fixed-effects structure. This is because its computation is based on the Cochran multivariate statistic, which is calculated based only on the fixed-effects model; see Cochran heterogeneity statistic in Methods...

District, sample size, and diagnostic target were significant predictors of bovine trypanosomiasis in univariate meta-regression models (p < 0.25) with district influencing heterogeneity the most (14.93% of variation). For all species except goats and domestic pigs, the national district explained...
