Study participants' flowchart, rural group.

1 Moved away / no longer resident was defined as those people who no longer live in the given address and moved to another area or are continuously living outside the area of study (e.g. house maids and security guards working and living full-time on employer’s houses/properties). This definition applies for all study groups.

2 Questionnaires completed, but no laboratory tests were done because required sample size was reached and limited funds.
