FIGURE 1.

Critical illness and all‐cause mortality stratified by platelet count, mean platelet volume (MPV; fL), and immature platelet fraction (IPF; %). A, Stratification based on low, normal, and elevated platelet count at hospital presentation and adjusted odds ratio for critical illness and all‐cause mortality based on platelet count. B, Stratification based on tertile of MPV at hospital presentation and adjusted odds ratio for critical illness and all‐cause mortality based on MPV. C, Stratification based on tertile of IPF at hospital presentation and adjusted odds ratio for critical illness and all‐cause mortality based on IPF. Covariates in the multivariable models included age, sex, race, body mass index, tobacco use, race‐ethnicity, hypertension, hyperlipidemia, chronic kidney disease, prior heart failure, asthma or chronic obstructive pulmonary disease, coronary artery disease, cancer, diabetes, temperature, SpO₂, and initial laboratory results for lymphocyte count, ferritin and C‐reactive protein, D‐dimer, creatinine, troponin, and procalcitonin
