Note. Change for intervention groups as a function of number of recommendations and intervention characteristics. Passive control groups (d = 0.15) were excluded. d = fixed-effects weighted means. Following the means, we present the QBs for each intervention characteristic alone and in interaction with the number of recommendation. QB for simple and main effects = homogeneity coefficient for the difference across levels of a factor, distributed as a chi-square with degrees of freedom equal to the number of factor levels − 1 degrees of freedom. QB for interaction = homogeneity coefficient for the interaction between factors, distributed as a chi-square with (number of levels of factor A − 1) × (number of levels of factor B − 1) degrees of freedom. ds with similar subscripts are not significantly different from one another.
