Unadjusted and adjusted Beta coefficients (95 % confidence interval) for mental (MCS) and physical (PCS) scores by number of comorbid chronic conditions among type 2 diabetes patients (n = 1676)
| Number of comorbid chronic conditions | |||||
|---|---|---|---|---|---|
| 1 n = 376 B (95 % CI)* |
2 n = 317 B (95 % CI)* |
3 n = 235 B (95 % CI)* |
4 or more n = 387 B (95 % CI)* |
