Odds ratios represent the unadjusted probability estimate of the italicized row in each recruitment center compared to NU/Lurie (reference group). Odds ratios for income are based on probability of earning > 100k versus <$50k and for asthma are based on having asthma (outgrown asthma, n=19 was excluded) versus not having asthma.
