Forest plot of restricted activity and hospitalisation. Analysis is sub-grouped by the type of restricted activity (bed rest and restricted movement). The square markers indicate the point estimate of the effect size within the different studies, with the whiskers indicating the confidence intervals. The size of the box correlates to the inverse variance of the effect estimate, which indicates the weight given to the study in the pooled analyses. Superscript denotes the control for each study. RR = Risk ratio, OR = Odds ratio, IR = Incident rate. *No pooled effect was estimated due to the lack of studies in each sub-group, and due to the non-significant study sizes
