Md Ali NA, ElAnsary D, Abdul Rahman MR, et al. Early Supervised Incremental Resistance Training (ESpIRiT) following cardiac surgery via a median sternotomy: a study protocol of a multicentre randomised controlled trial. BMJ Open 2023;13:e067914. doi:10.1136/ bmjopen-2022-067914

This article has been corrected since it was published online. Figure 1 Flow chart indicated we added two time points to before discharge destination as our original protocol specifies one time point. The correct supplementary Figure 1 is shown below. Additionally, we have left out the word ‘post’ which should have been written as post-operative period text prior to discharge at day 7 (+1 day) in the inpatient setting across centres, and at the outpatient setting at 4 weeks (+14 days) and 3 months (±14 days). These changes to the protocol manuscript do not impact on the methodology of the manuscript.
