  1. AThe data for these calculations were based on the findings of the fourth round of screening which is available in the data supplement of ref. 9.
  2. BThe source publication10 does not present findings for each of the 3 screening rounds separately. The numbers here reflect the mathematical average of all 3 rounds. For example, although 53418 women underwent at least one CBE, the average per round was 38798 [50366 in round 1 +34534 in round 2 +31495 in round 3 = 116395. 116395/3 is an average of 38798 women screened per round].
