Introduction: Pakistan ranks fifth in the globally estimated burden of Tuberculosis (TB) case incidence. Annually, a gap of 241,688 TB patients exists between estimated TB incidence and actual TB case notification in Pakistan. These undetected/missed TB cases initiate TB care from providers in the private healthcare system who are less motivated to notify patients to the national database that leads to significant under-detection of actual TB cases in the Pakistani community. To engage these private providers in reaching out to missing TB cases, a national implementation trial of the Public-Private Mix (PPM) model was cohesively launched by NTP Pakistan in 2014. The study aims to assess the implementation, contribution, and relative treatment outcomes of cohesively implemented PPM model in comparison to the non-PPM model. Methods: A retrospective record review of all forms (new and relapse) TB patients notified from July 2015 to June 2016 was conducted both for PPM- and non-PPM models
