Predictors of PH in COPD patients using adjusted logistic regression models

Variables	OR	95% CI	P
PLT	1.02	(1.0077–1.0300)	0.001
MPV	6.70	(4.1205–10.8903)	<0.001
TLC	0.98	(0.7376–1.2944)	0.87
FEV1	0.99	(0.9673–1.0122)	0.37
Exacerbation frequency	0.59	(0.3454–1.0122)	0.051

Notes: Pearson; X²=210.5, P=0.9, the model was adjusted for all variables using stepwise elimination.

Abbreviations: COPD, chronic obstructive pulmonary disease; FEV1, forced expiratory volume in the first second; MPV, mean platelet volume (fL); PH, pulmonary hypertension; PLT, platelets count; TLC, total leucocytes count.
