Abbreviations: OR, Odds Ratio; CI, Confidence Interval; Inf, Infinity.

^aOdds Ratios and 95% Confidence Intervals were calculated based on a 10-unit increase for three EHI variables. Reference is the reference category of the variable.

^bp-Values<0.05 are in bold.

^cGED denotes a General Educational Development Certificate, which is awarded in lieu of a high school diploma.

^dEHI denotes economic hardship index: a validated measure of neighborhood socioeconomic status standardized on a scale from 0–100 in which higher scores indicate higher hardship.⁸ The education subscale is based on the percentage of individuals in a community with no high school diploma or equivalent, while the poverty subscale is the percentage below the poverty level.
