Rank deficient coefficients were removed from the model by the lmer function (e.g. if one study only included females and no males).
N number of, CI confidence interval.
^aIntervention effects (ACT vs. control) in strata of low, medium, and high levels of EBTs on percentage weight change were estimated while stratifying all other parameters by trial.
^bInteractions between randomised group (ACT vs. control) and EBTs on percentage weight change were estimated while stratifying all other parameters by trial.
^cReference group was medium levels of each EBT, respectively.
