Fig. 1From: Marijuana use and DNA methylation-based biological age in young adultsEstimated parameters by quantile with 95% confidence limits for the effect of cumulative and recent marijuana use on GrimAge acceleration at examination years 15 and 20. Quantile regression plots at Y15 and Y20 for A cumulative and B recent use of marijuana. The x-axis represents the quantile scale, and the y-axis represents the effect of marijuana use on GAA for a given quantile. Results are adjusted for sex, race, center, education, tobacco smoking status, cumulative packs of cigarettes, BMI, physical activity, and alcohol consumption, with cumulative marijuana analyses further adjusted for ever marijuana useBack to article page
