Longitudinal study: TG levels remarkably declined, and the correlation with disease severity weakened over time in the HTG-AP patients. A The TG level changed after the onset of symptoms from 24 h to 5-7 d. B The difference in TG levels in MAP, MSAP and SAP patients during the onset time of 24 h to 5-7 d. Data are presented as the medians (IQR, 25th-75th percentile). The 24 h, 48 h, 3-4 d, and 5-7 d are based on duration between the time of onset to when the TG levels were measured in HTG-AP patients. TG, triglyceride; HTG-AP, hypertriglyceridaemia-induced acute pancreatitis; MAP/MSAP/SAP, mild/moderately severe/severe AP; IQR, interquartile range. * significance when compared among different onset times (P < 0.050). §§ significance for both in MSAP and SAP disease when compared with MAP disease (P < 0.050). § significance only for SAP disease when compared with MAP disease (P < 0.050)
