  1. A positive coefficient of an estimate indicates that the mean of hearing loss increase with the value of the potential risk factor. The higher the estimate the higher the hearing loss
  2. Reference categories: HIV = 0 and NCD (Hypertension and Diabetes) = 0
  3. LFPTT, Low-frequency pure tone thresholds; MFPTT, Mid-frequency pure tone thresholds, HFPTT, High frequency pure tone thresholds; EHFPTT Extended high-frequency pure tone thresholds
