The regression designs was indeed adjusted for the standard attributes computed for the the univariate research

Mathematical data

Investigation off each BPD severity group have been compared using one-method ANOVA, brand new Kruskal–Wallis take to getting carried on research, new chi-rectangular test otherwise Fisher’s specific attempt to have categorical parameters, otherwise z testing with correction for continuity to possess size.

To regulate the fresh new organization ranging from per BPD meaning and you will results for prospective covariates, multivariate logistic regression is did for every severity class to help you guess chances proportion (OR) with a beneficial 95% rely on interval (CI). Sensitivity, specificity and you may positive and negative predictive viewpoints were calculated getting breathing ailment, GMFCS score, and you will NDI using multivariable logistic regression.

The fresh fit of the patterns was verified into the Hosmer–Lemeshow god of-fit attempt. Every analyses have been performed with the software program SPSS adaptation twenty-four.0 (SPSS Inc., Chicago, IL, USA). In every analyses, a p really worth less than 0.05 are noticed mathematically high.
