Timeline of surveys and intervention.
1 WRA = Women of Reproductive Age defined here as between 16–45 years. 2 Hb = Hemoglobin, sFe = serum Ferritin, STH = Soil transmitted helminthes. 3 WIFS = Weekly Iron Folic acid Supplementation.

Flowchart of participant follow up.
Those lost to follow up did not re-present at any later survey. Of the 389 baseline cohort women, 288 (74% and the sum of the ovals horizontal from the 54 month survey rectangle) returned for the 54-month survey of whom 124 attended every survey as shown by the direct connecting line from Baseline to the 54 month follow-up. The other 164 women who attended the 54 month survey missed one or more intermediate surveys but were contacted and followed up subsequently. For example, 48 women who attended the Baseline survey missed the 3 month survey but did attend at 12 months. Of these, 41 attended at 30 months and 34 of them attended at 54 months. Another two women from the 12 month survey missed the 30 month survey but attended at 54 months.
