Additional file 6 Table A4 Study population QFT conversion analysis using conversion definition 2 (< 0.2, ≥0.7). a End point follow-up was placed halfway visits for contacts who converted, and was the date of the last negative QFT measurement for contacts who did not convert. To account for uncertainty between the follow-up QFT measurements, analysis time was split into visit 1-visit 2 and visit 2-visit 3. b A random variable allocated approximately 50% of contacts with unknown visit 2 status and conversion at visit 3, to have end point follow-up halfway visit 1-visit 2 and ~ 50% half-way visit 2-visit 3. This was informed by the distribution of QFT conversion between visit 1–2 and visit 2–3 among contacts with an available QFT measurement at visit 1, 2, and 3.
