APOA1 and alkaline phosphatase measurement: A decrease in apoA-I concentration in this group of AP patients was accompanied by gradually decreasing PON1 concentration (p = 0.0080 and p < 0.0001 for comparison on the first day with the third and the seventh days), which was statistically significant compared to AP patients with the TC genotype (p = 0.0045 on the first day and p = 0.0002 on the seventh day).
