Network plot of evidence. The thickness of lines is proportional to the precision of each direct estimate and the size of circles is proportional to the number of participant randomised to that treatment. The N indicates the number of participants who were randomly assigned to each delivery format. Delivery formats are represented as green nodes, while controls are in grey. The nodes are circled in red where the CBT was delivered ‘in-presence face-to-face’, and in blue if the delivery was ‘by remote’. No trial delivered treatment through the individual or group remote synchronous modality.
