ABSTRACT Meta-analysis is a common statistical method used to summarize multiple studies that cover the same topic. It can provide less biased results and explain heterogeneity between studies. Although there exists a variety of meta-analysis software, they are rarely both convenient to use and capable of comprehensive analytical functions. As a result, we established a meta-analysis web tool called Meta-Analysis Online (Onlinemeta). Onlinemeta includes both risk bias analysis and meta-analysis. The risk bias analysis tool can produce heatmaps and histograms, whereas the meta-analysis tool can be used to analyze dichotomous variables, single-armed dichotomous variables, continuous variables, single-armed continuous variables, survival data, and diagnostic experiments. In addition, it can be used to generate forest plots, funnel plots, SROC curve, and crosshair plots. Onlinemeta can be found at the following address: https://smuonco.Shinyapps.io/Onlinemeta/ .
