From: The effect of telemedicine in critically ill patients: systematic review and meta-analysis
Subgroup analyses of effect of telemedicine on ICU mortality based on intensity of the intervention (continuous patient-data monitoring, with or without computer-generated alerts (active or high-intensity passive systems), in upper panel, and neither present (low-intensity passive systems) in lower panel). Pooled risk ratios were calculated by using a random-effects model. Weight refers to the contribution of each study to each subgroup's estimate of treatment effect. The interaction p value for the difference between risk ratios is 0.74.
