CNMA-UpSet plot for the psychological preparations dataset. In the matrix of dots in the bottom-right hand corner each row represents a component and each column represents an intervention. The solid vertical lines connecting dots within a column indicate which components are included in each intervention. If an intervention consists of a single component there is no vertical line. Above the matrix of dots, a vertical bar chart represents the number of trial arms for each unique intervention. To the left of the matrix of dots, a horizontal bar chart represents the number of trial arms including each specific component (regardless of whether it was included in isolation or in combination with other components). E = emotion-focused techniques, R = relaxation, C = cognitive interventions, S = sensory information, P = procedural information, B = behavioural instruction, UC = Usual care
