The primary meta-analysis produced a sample-weighted odds ratio, or, of 0.62 in favor of digital interventions decreasing the risk of alcohol consumption during pregnancy when compared to controls, with computer-slash-internet-based interventions being an effective platform for preventing alcohol consumption.
