Sensitivity analyses Four sensitivity analyses will be conducted. In the first sensitivity analysis the investigators will only include observations with complete outcome data, however missing values in covariates were allowed. In the second sensitivity analysis the investigators will exclude observations without any reported injury. In the third sensitivity analysis the investigators calculated cICISS and swiICISS based on all available SRRs, regardless of how frequently the corresponding ICD-10 codes occurred in the dataset. Finally, the investigators calculated the two ICISS scores for each patient based only on unique ICD-10 codes. In other words, each ICD-10 code was only allowed to contribute with one SRR to the ICISS scores even if it occurred more than once in the same patient.
