Note: Based on a person‐year survival analysis controlling for AOO, time since onset, age at interview, sex, time‐varying education, time‐varying marital status, and time‐varying migration status, All treatment models used Part II weights. Analysis restricted to the subset responding to the long interview (n = 2583). Respondents who said they did talk to a medical doctor or other professional AND did not report their age of first treatment were excluded from the LT treatment analyses (n = 8).
