Osei-Atweneboana, Orin Courtenay, Petr VolfA. SOD values of the IgG ELISA for negative control samples (n = 35) from Accra and Bono East region residents (n = 958), Ghana. The cut-off value is shown by a dashed horizontal line and is equal to 0.275 SOD. B. SOD values of the IgM ELISA for negative control samples (n = 33) and Bono East region residents (n = 500). The cut-off value is shown by a dashed horizontal line and is equal to 0.998 SOD. The solid black horizontal line within the boxes is the median; the lower and upper borders are, respectively, the 1st (Q1) and 3rd (Q3) quartiles; the vertical bars indicate the ‘minimum’ and ‘maximum’ values, calculated as Q1–1.5 × IQR (interquartile range) and Q1 + 1.5 × IQR, respectively.
