**BPH = Benign Prostatic Hyperplasia
***High Neighborhood Exposure Score was calculated as the weighted sum of the final significant neighborhood socioeconomic variables (nSES; values weighted by the penalized coefficients from the final patient plus neighborhood-level models) in the total population and each race-specific group. Neighborhood exposures were dichotomized at the median to categorize participants as residing in a neighborhood with either high or low exposure to significant neighborhood socioeconomic conditions.
