Plasma OP residues correlate with fecal esterase activity and fecal acetate. Fecal samples were collected from control (n = 60) and diabetic (n = 60) humans. a Fecal esterase activity of non-diabetic vs. diabetic individuals. b Regression plot of plasma total OPs vs. fecal esterase activity. c Fecal acetate level of non-diabetic vs. diabetic. d Regression plot of plasma total OPs vs. fecal acetate content. Horizontal lines represent mean; error bars represent s.e.m; *P < 0.05 Rank sum, Mann–Whitney U Test (a, c). The hollow circle represents individual values and straight line represents the trend line. PCC Pearson correlation coefficient, β regression coefficient. *P < 0.05; **P < 0.01
