^†Promise ratio denotes the number of very or quite-promising interventions in which a behaviour change technique occurred divided by the number of non-promising interventions in which it featured. Rows in bold denote BCTs associated with a promise rate > 2 or used in promising interventions in at least two interventions

^‡If a BCT only appeared in promising interventions and in at least two intervention, the number of interventions in which it appeared is reported in italics
