Categorical medical outcomes were adjusted for study site if there was sufficient cell size (≥5 per group) and statistically significant associations with NNNS profiles (p<.05).
Notes: For continuous medical data, data are unstandardized coefficients from linear regression analysis; for categorical medical data, data are odds ratios from logistic regression analyses
