Meta-analysis of median survival times with inverse-variance weighting
Sean McGrath, Cheng-Han Yang, Jonathan Kimmelman +3
We consider the problem of meta-analyzing outcome measures based on median survival times. Primary studies with time-to-event outcomes often report estimates of median survival tim…
metamedian: An R package for meta-analyzing studies reporting medians
Sean McGrath, XiaoFei Zhao, Omer Ozturk +3
When performing an aggregate data meta-analysis of a continuous outcome, researchers often come across primary studies that report the sample median of the outcome. However, standa…
Standard error estimation in meta-analysis of studies reporting medians
Sean McGrath, Stephan Katzenschlager, Alexandra J. Zimmer +3
We consider the setting of an aggregate data meta-analysis of a continuous outcome of interest. When the distribution of the outcome is skewed, it is often the case that some prima…
Revisiting the g-null paradox
Sean McGrath, Jessica G. Young, Miguel A. Hernán
The parametric g-formula is an approach to estimating causal effects of sustained treatment strategies from observational data. An often cited limitation of the parametric g-formul…
Estimating the sample mean and standard deviation from commonly reported quantiles in meta-analysis
Sean McGrath, XiaoFei Zhao, Russell Steele +4
Researchers increasingly use meta-analysis to synthesize the results of several studies in order to estimate a common effect. When the outcome variable is continuous, standard meta…
Two-sample aggregate data meta-analysis of medians
Sean McGrath, Hojoon Sohn, Russell Steele +1
We consider the problem of meta-analyzing two-group studies that report the median of the outcome. Often, these studies are excluded from meta-analysis because there are no well-es…
One-sample aggregate data meta-analysis of medians
Sean McGrath, XiaoFei Zhao, Zhi Zhen Qin +2
An aggregate data meta-analysis is a statistical method that pools the summary statistics of several selected studies to estimate the outcome of interest. When considering a contin…
