Abbreviations: OR, odds ratio; POPC, Pediatric Overall Performance Category.
The largest group within each variable was chosen as the reference category.
An OR of greater than 1.0 indicates higher odds of missed school during hospital admission to 6 months after discharge. Odds ratios were calculated using logistic regression.
Disability was determined using the POPC. A score of 1 indicates a good functional status, while a score of 2 or greater represents at least mild disability.
An OR of greater than 1.0 indicates higher odds of missed school during hospital admission to 6 months after discharge. The OR describes the change in odds of increasing categories of duration of school absence, calculated using ordinal logistic (proportional odds) regression.
