  1. Bold values represent a statistical correlation between biomarkers (p < 0.05). Correlations were calculated for UF and F fractions whatever the site (A) and for each site whatever the size fraction (B). Total table was calculated with all results of Bamako and Dakar samples for the 3 class fractions.
