|---|---|---|---|---|
| Practice type predicting distress: Overall model (n = 605)* | 10.7 | 0.004 | ||
| Intercept | 1.94 (0.07) | <0.001 | ||

Abbreviation: SE, standard error.
↵*11 have missing DDS-17_Total so are out of the type only model (605).
↵**Practice type was dummy coded FQHC = 0 and Non-FQHC = 1. Adjusted model includes practice type and SDOH variables remaining after reverse selection with alpha = 0.05.
↵***17 have other missing values (16 missing language, 1 missing age) and are removed from the expanded model (588).
