The correlation between OI and OSI was analyzed by using the Pearson correlation coefficient.<\/jats:p><jats:p>\n            Results\u2003A total of 636 measurements from 68 neonates (35 preterm and 33 terms) were recruited into the study. There was a strong correlation between the OI and the OSI (r\u2009=\u20090.90) in all neonates. The correlation between the OI and the OSI in persistent pulmonary hypertension of the newborn, congenital cyanotic heart disease, and other causes of respiratory failure also showed a strong correlation (r\u2009=\u20090.88, 0.93, and 0.88, respectively). The correlation was strong in neonates with an oxygen saturation less than 85% (r\u2009=\u20090.88), those with oxygen saturation ranging from 85 to 95% (r\u2009=\u20090.87), and also in preterm and term infants (gestational age\u2009&lt;\u200928, 28\u2009\u2212\u200934, 34\u2009\u2212\u200936, and \u226537 weeks, r\u2009=\u20090.87, 0.92, 0.89, and 0.90, respectively). There were strong accuracy measures of the OI for OI cutoffs of 5, 10, 15, and 20 (area under the curve\u2009&gt;\u20090.85). The equation relating the OI and OSI was represented by: OI\u2009=\u2009(2.3\u2009\u00d7\u2009OSI) \u2013 4.<\/jats:p><jats:p>\n            Conclusion\u2003The OSI has a strong correlation with the OI, is a reliable assessor of the severity of respiratory failure in neonates without arterial sampling, and has high accuracy when the OI is less than 40.<\/jats:p><jats:p>\n            Key Points\n
