Similarly, there was a higher probability of developing ARDS among those with higher number of risk factors (Ptrend < 0.001), with approximately one out of six patients with all risk factors (age ≥ 50 years, BMI ≥ 27.4 kg/m2, lymphocyte count ≥1400 cells/μL, and CRP ≥ 4.0 mg/dL) developing ARDS vs. none of those without any or only one of these risk factors. This evidence concerns the gene CRP and acute respiratory distress syndrome.
