- aP value is not presented because generalised linear mixed-effects model does not support analysis for categorical data. Data are presented as (b) mean ± SD, (c) total number and proportion. * A (comparison between < 3 & 24 h), B (comparison between < 3 h & 6 days), and C (comparison between 24 h & 6 days)
