Note: *Two-tailed independent t test. #Two-tailed chi-square test. Abbreviations: RSHSI, Recessive Spherical Headed Silicone Intubation. En-DCR, Endonasal Dacryocystorhinostomy. CI, Confidence Interval. n1 = the number of operative eyes in each group. Right: left was analysed based on n1. n2 = the number of NLDO patients in each group. Age, history and gender were analysed based on n2.
