Questions about the shape of the dose-response relationship are commonly asked based on multiple tables of aggregated and correlated estimates. The aim of this Cochrane Learning Live webinar was to provide an understanding of weighted mixed-effects models and how to conduct statistical inference on marginal and conditional quantiles of the dose-response relation. Simulated and real examples were used to illustrate possible applications of the statistical model as well as statistical software.

The session was aimed at statisticians and meta-analysts with some familiarity with random-effects regression models and meta-analysis.

The webinar was delivered in March 2022 and below you will find the video from the webinar, together with accompanying slides to download [PDF].
