P1 value, the p value of comparisons between the group with osmolarity <285 mmol/L and the group with osmolarity in 285–300 mmol/L.
P2 value, the p value of comparisons between the group with osmolarity >300 mmol/L and the group with osmolarity in 285–300 mmol/L.
LOS, length of stay; IQR, interquartile range.
