Note. Positive D within indicates a reduction in drinks per week from baseline to follow-up. Bold font indicates statistically significant weighted mean difference. D within = raw mean difference; GS = gender-specific; PNF = Personalized Normative Feedback; k = number of interventions; FU Wks = number of weeks from baseline to first follow-up; CI = confidence interval.
