From: ROX index as a predictor of failure of high-flow nasal cannula in infants with bronchiolitis
Evolution of physiological variables, including the ROX index, during the 7 evaluation times and the differentiation between patients who had failure (solid line) and success (dashed line) in HFNC therapy. p values are only presented when there is a significant difference between the groups, and the absence of mention indicates no significant difference. **p < 0.05, #p < 0.01, *p < 0.001. The values are expressed as estimated means and 95% confidence intervals (95% CI) obtained through generalized mixed models (moments from before to 24 h) and generalized linear models (removal moment. The removal time was adjusted for the time of use of HFNC therapy.
