Mean platelet volume as a predictive biomarker for in-hospital mortality in patients receiving invasive mechanical ventilation

Table 4 Relationship between in-hospital mortality and MPV cutoff by sex

In-hospital mortality	Female		Male
In-hospital mortality	HR (95%CI)	P	HR (95%CI)	P
MPV > 11.4 fl	14.265 (2.323–87.579)	0.004	2.905 (1.042–8.098)	0.042

Covariates included in Cox model: APACHE II score, CRP, PaO2/FIO2, vasopressor use, CRRT, CKD, AKI, septic shock
MPV mean platelet volume; APACHE II acute physiology and chronic health evaluation II; CRP C-reactive protein; CRRT continuous renal replacement therapy; CKD chronic kidney disease; AKI acute kidney injury; PaO₂ arterial oxygen tension; FiO₂ fraction of inspired oxygen; HR hazard ratio; CI confidence interval
