Parameters

Parameter: Annual number newly initiated onto treatment

  • Code name: initiate

  • Value can be used for calibration

  • Units/format: number

  • Value restrictions: At least 0

  • Contributes to transitions from:

    • “Diagnosed, not treated” to “Treated”

  • Default value: None

  • Appears in the databook

  • Description:

  • Data entry guidance:

Parameter: Annual number lost to follow-up

  • Code name: num_loss

  • Units/format: number

  • Value restrictions: At least 0

  • Default value: None

  • Appears in the databook

  • Used to compute:

    • “Proportion of those on treatment lost-to-follow-up”

  • Description:

  • Data entry guidance:

Parameter: Proportion of those on treatment lost-to-follow-up

  • Code name: loss

  • Value can be used for calibration

  • Units/format: probability
