Anti-gSG6 humoral response in the ethnic groups Mossi and Fulani.

<p><b>(A)</b> Box plot of OD values among responders in the seven different surveys (Mossi, empty boxes; Fulani, grey boxes). The number of Mossi (M), Fulani (F) and the average age ±95% CI were as follows: August ’94 M = 104 (16.1±3.1), F = 93 (13.8±2.6); October ’94 M = 92 (13.4±2.8), F = 43 (17.7±5.2); March ’95 M = 46 (18.7±4.9), F = 45 (11.2±3.1); August ’95 M = 146 (16.1±2.8), F = 92 (11.0±1.6); October ’95 M = 127 (12.8±2.2), F = 106 (17.8±3.1); August ’96 M = 41 (13.6±3.6), F = 42 (12.7±3.2); October ’96 M = 56 (14.5±3.2), F = 115 (17.3±3.1).
