Competing Interests
The authors have read the journal's policy and have the following conflicts. 1. The parent study referred to in the manuscript was funded by Anglogold. 2. Aurum Health Research, which at the time was a wholly owned subsidiary company of AngloGold Health Services, provided salary support to KF, SC, JD and GJC. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
