From: Prevalence, risk, and outcome of deep vein thrombosis in acute respiratory distress syndrome
Prevalence of DVT decreased with serum creatinine levels only in the direct ARDS group. The occurrence of DVT in the direct ARDS group (red line) decreased with increasing serum creatinine levels, whereas serum creatinine levels had no association with DVT in the indirect ARDS group (blue line; test for interaction, P = 0.006). Data are adjusted for age, procalcitonin levels, D-dimer levels, PaO2/FiO2, and invasive mechanical ventilation. Abbreviations: ARDS, acute respiratory distress syndrome; DVT, deep vein thrombosis; FiO2, fraction of inspired oxygen; PaO2, partial pressure of arterial oxygen
