‡
For this variable, the result presents median with 10th percentile and 90th percentile in the parenthesis for each cohort. The p-value was obtained by Mann–Whitney U test.
#
For this variable, the p-value was obtained by Fisher’s exact test.
c
It denotes that a significant relationship (p<0.05) was detected between cohort 1 and cohort 3. It was done by Fisher’s exact test for categorical variable, or by Dwass, Steel, Critchlow-Fligner method for continuous variables. No other significant result was obtained from the pairwise comparison analyses.
