A protocol was therefore written to conduct a study to measure IPT completion rates and evaluate predictors of non-completion of a six-month IPT course in Khayelitsha, an informal township in Cape Town. Prior to data analysis, a structured literature review was conducted to assess available evidence particularly from high-burden settings on IPT completion rates and factors associated with loss to follow up
