Do I really talk that slow? Try playing at 1.25x or 1.5x speed (see playback settings).

This week we’re going to figure out whether running is bad for your knees using meta-analysis, which lets you combine the results of multiple studies or experiments and see if they’re consistent.

Here's the code I used for this one: https://github.com/calebclass/DataViz...

This article provides an introduction to the use of Odds Ratios in case-control studies: https://doi.org/10.1136/bmj.320.7247....

You can find a great meta-analysis tutorial here. It provides examples of meta-analysis for ecological data, but it applies to all sorts of data: https://bookdown.org/robcrystalornela...

And for more info about running & your knees, here's some people who know what they're talking about:    • Is Running Bad for Your Knees… or Actually...
