Bold font indicates statistically significant results. P values and OR were based on a continuous variable for age at death and dichotomous variables in all other analyses. Percentage (%) of suicidality relative to the number of participants with documented suicidality in somatic records during their care (n=111) within each subgroup.
*Missing data: information about civil status for 96 patients and information about employment for 124 patients.
†Documentation of experience of distress in medical records.
‡Other care providers, as noted in somatic medical records.
§Diagnosis according to ICD-10, chapter V (codes F00-F99), documented in medical records, used to define psychiatric comorbidity.
¶Two or more diseases according to ICD-10, chapters I-IV, VI, VII/VIII, IX–XIV, used to define multiple physical conditions.
