Studies	Lipid features in COVID-19 patients	References
A retrospective study of 597 patients from Union Hospital of Tongji Medical College, Wuhan	↓ LDL-c, HDL-c, TC and TAG in severe vs mild disease	Wei et al. [167]
A retrospective study of 21 patients at Zhongnan Hospital of Wuhan University in Wuhan	↓ LDL-c, HDL-c, and TC in severe vs mild disease LDL returned to pre-infection level upon recovery	Fan et al. [168]
A retrospective study of 71 patients at Wenzhou Central Hospital, Wuhan	↓ LDL-c, HDL-c, and TC in COVID-19 patients vs healthy	Hu et al. [222]
A retrospective study of 114 patients at Wenzhou Central Hospital, Wuhan	Significant ↓ LDL-c, HDL-c, TAG and TC in COVID-19 patients vs healthy Significant ↓ HDL-c in severe vs COVID cases	Hu et al. [12]
A retrospective analysis of 228 COVID patients at Public Health Treatment Center of Changsha, China	↓ LDL-c, HDL-c in with disease severity	Wang et al. [223]
A clinical data collected from 70 patients at Yeungnam University Medical Center, Republic of Korea, as part of a sterol regulatory element binding protein-2 (SREBP-2) study	↓ LDL-c, HDL-c in severe vs mild	Wonhwa et al. [224]

HDL-c = high-density lipoprotein cholesterol, LDL-c = low-density lipoprotein cholesterol, TC = total cholesterol, TAG =triacylglycerol.
