Effect-size estimates of MRR and monocytes for mortality as categorical variable in the derivation cohort.

Parameters	Case/Total	Survival rate, %	Unadjusted HR (95% CI)	Adjusted HR (95% CI)
MRR
Reference group	100/168	22.57	Reference	Reference
Risk group	53/80	12.93	1.40 (1.00–1.96)	1.56 (1.02–2.37)
Monocyte
Reference group	119/200	20.66	Reference	Reference
Risk group	34/49	13.83	1.53 (1.04–2.24)	1.90 (1.16–3.11)

MRR, monocyte-to-red blood cell count ratio; HR, hazard ratio; 95% CI, 95% confidence interval. Effect-size estimates were calculated under the COX proportional hazard regression models.

Adjusted HR was adjusted for age, gender, FVC (% predicted), DLCO (% predicted), Charlson Comorbidity Index, and drug therapy (steroids, N-acetylcysteine). P was calculated by Kaplan–Meier analysis. Cutoff values: 0.13 for MRR, 0.67 for monocyte.
