Group1A included treatment-requiring ROP (TR-ROP), and group 2A included the remaining patients not requiring treatment. Group 1B included stage 3 ROP cases, and group 2B included the remaining stage 2 or 1 ROP cases. Group 1C included cases with zone III disease, and group 2C the remaining. The control group (group C) was composed of premature infants without ROP. The multiple comparisons were made among groups 1A, 2A, and C; 1B, 2B, and C; 1C, 2C, and C.Results A total of 311 infants were included. Group 1A included 34 cases, group 1B 60, group 1C 51, and group C 98. Antenatal steroid administration, gestational diabetes mellitus (GDM), gestational weight (GW), gestational age (GA), sepsis, continuous positive airway pressure (CPAP) time, and invasive mechanical ventilation (MV) time were associated with TR-ROP, stage 3 ROP, and zone I, and II disease (p?<?0.05). Pregestational diabetes mellitus (DM) was only associated with stage 3 ROP (p?=?0.031). Gestational hypertension was only associated with zone I and II disease (p?=?0.034). The use of low-molecular-weight heparin may be protective against stage 3 disease (p?=?0.031).Conclusion Antenatal steroid administration, GDM, GW, GA, sepsis, CPAP time, and invasive MV time were risk factors for TR-ROP and stage 3 ROP, while pregestational DM was only associated with stage 3 ROP. 收起
