For patients between five years of age or older, severe immunosuppression was defined as an initial CD4 count less than 200 cells/mm3 or percentage less than 15%, moderate immunosuppression as an initial CD4 count of between 200 and 500 cells/mm3 or percentage of between 15% and 25%, and no immunosuppression as an initial CD4 count of 500 cells/mm3 or more, or percentage of 25% or more.
21 point assigned for each service received (screened for tuberculosis, adherence counseling at last visit, adherence measured by patient/caregiver self-report at last visit, ever prescribed co-trimoxazole, alive and not lost to follow-up with at least one CD4 count in the last six months, and weight documented in chart at patient's last visit, and 0 points assigned if the service was not received, for a total of 6 points. A high score was defined as having the median score or above (>4 points).
