Fig 5. Association of median titres of S. haematobium-specific antibodies with age.

Association of median titres of S. haematobium-specific antibodies (A–I) with age at baseline and Follow-up among participants infected with S. haematobium at baseline (N = 26). Horizontal lines within the boxes (or those bisecting whiskers) denote the median levels. The lower horizontal border of the box represents the 25^th percentile, whilst the upper boarder denotes the 75^th percentile. The upper and lower whiskers are set at the 95^th and 5^th percentiles respectively. The Wilkoxon Matched-Pairs Signed-Ranks test was employed in determining p-values.
