LOS, length of stay; , number; SD, standard deviation. No adjustment beyond the propensity score matching was conducted. Beta-estimates (95% CI) for each statistical comparison are provided within Table 4. comparator group within this table was composed of eligible non-ICC patients that were propensity score-matched to an ICC patient. Patients were matched on patients’ gender, age, the fiscal quarter in which they were discharged from the hospital for a COPD admission, and number of prior admissions in the last 60 days. patients still admitted at the end of the examined time-horizon, the complete LOS was included in the analysis even if it extended beyond the examined time-horizon. value within the negative binomial part of the ZINB regression. value within the zero-inflated part of the ZINB regression.
