The Charlson Index was calculated using ICD-9 codes from clinical diagnoses. Total score is categorized as a binary variable
ICD-9: 290-319 excluding depression diagnoses (ICD-9 codes: 2962, 2963, 296.82, 2980, 3004, 301.12, 3090, 3091, 309.28, 311)
Subtracting BMI measured on the earliest date from the BMI measured on the latest date prior to the index date
Note: Index date refers to date of suicide death
