The evidence geekery continues, and this week Helen Macdonald and Duncan Jarvies are joined by Joe Ross, The BMJ's US research editor, and professor of medicine and public health at Yale.

This week we pick up on a preprint in medRxiv, which has been attracting attention on social media - it tries to look at the longer term effects of covid hospitalisation.

Joe explains why he thinks propensity matching can be summarised as "doing your best".

Finally, as more and more care moves remotely, we discuss a trial on a digital intervention to help manage poorly controlled hypertension remotely.
