Box plots of changes in SOFA scores and PaO2/FiO2 over time. Circles represent data below 1.5 × IQR of the lower quartile or above 1.5 × IQR of the upper quartile. (a) SOFA scores. The number of patients for each day point is 23 for each group since the first censored case is at day 14. (b) PaO2/FiO2 ratios. The numbers of patients analyzed for each day point are the following: 23 vs. 23 (day 1), 23 vs. 23 (day 3), 23 vs. 23 (day 5), 23 vs. 22 (day 7), 18 vs. 21 (day 9), 12 vs. 14 (day 14), which is noted as “the study group” vs. “the control group”.
