Analytical studies

Research regarding for each BPD seriousness group was indeed compared using one-way ANOVA, the fresh Kruskal–Wallis try getting continuous data, brand new chi-square try or Fisher’s appropriate take to to have categorical details, or z testing which have correction to possess continuity to possess size.

To regulate the fresh new relationship between for every single BPD definition and you can outcomes for prospective covariates, multivariate logistic regression was did per severity class in order to estimate the chances proportion (OR) that have a beneficial 95% count on interval (CI). Susceptibility, specificity and you will positive and negative predictive philosophy were determined to have breathing disorder, GMFCS rating, and you may NDI using multivariable logistic regression.

The latest complement of your designs is confirmed toward Hosmer–Lemeshow goodness away from-match attempt. All of the analyses were performed by using the computer software SPSS adaptation twenty four.0 (SPSS Inc., Chi town, IL, USA). In most analyses, a good p really worth less than 0.05 try thought statistically tall.
