Calculating the combined risk ratio of ROP i.e., estimating the risk ratio of retinopathy in preterm infants who had all three risk factors (familial parental marriage + birth week less than 32.5 + birth weight less than 1725 gr) showed that premature infants who had all three of these risk factors were about 52.7 times more likely to develop retinopathy as compared with infants without these risk factors (OR = 52.727, 95% CI: 16.597-167.507, P <0.001).	cache/bam-10063.pdf	txt/bam-10063.txt
