Linear regressions predicting gambling spend at follow-up. Note: Spending variables were log base 2 + 1 transformed to reduce positive skew. RLI scores were standardized. A shows the relationship between RLI scores and gambling spend at follow-up. B and C show the linear regression line for the effect of loot box and DPM spending on gambling spend at follow-up without controlling for either variable. D plots the standardized residual of loot box spending after regressing on DPM spending allowing for the visualization of the effect of DPMs when controlling for loot box spending
