The total of cases per variable does not always correspond with the total of patients, as there is no data record for some patients.
*Value “0” or “1” before the modality of each variable indicates the codification used for the analysis, assigning value “1” to the category exposed to risk and “0” to the basal or reference category.
**The priority distinguishes the severity level or triage performed with the Spanish Triage System (STS).
