| Etiology | OR* | 95% CI | P |
|---|---|---|---|
| Unadjusted model | |||
| CKD | 4.20 | 0.962-18.3 | .056 |
| MDS | 1.27 | 0.387-4.17 | .693 |
| AUE | 3.24 | 0.849-12.4 | .085 |
| Adjusted model, EPO linear† | |||
| CKD | 3.60 | 0.815-15.9 | .091 |
| MDS | 1.61 | 0.472-5.47 | .448 |

*
OR of treatment response is relative to other etiology.
†
Includes only EPO level as a confounder. Sex, age, weight, comorbidity index, hemoglobin, eGFR, and presence of another cytopenia were not found to be statistically significant predictors of response.
