All extractions were completed by a single reviewer and checked by a second reviewer. Quality appraisal was carried out using the mixed-methods appraisal tool, covering mixed-methods, qualitative and quantitative study designs. Narrative synthesis was carried out by tabulating and summarising studies according to PPM models and reported in line with the synthesis without meta-analysis guidelines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 57 included studies, covering quantitative (n=41), qualitative (n=6) and mixed-method (n=10) designs, the majority were from Southeast Asia (n=37). PPM models had overall positive results on TB treatment outcomes, access and coverage and value for money. They are linked with improved TB health workers\u2019 skills and service delivery. Most outcomes tended to favour interface models, although with considerable heterogeneity. Inconsistent implementation of national TB guidelines, uncoordinated referrals and lack of trust among partners were identified as areas of improvement. Evidence was lacking on the involvement of informal providers within PPM models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PPM models can be effective and cost-effective for TB care in urban low- and middle-income countries contexts, particularly when levels of mistrust between public and private sectors are addressed through principles of equal partnership.
