From: Mercury levels in hair are associated with reduced neurobehavioral performance and altered brain structures in young adults

Fig. 1

Partial residual plots with the trend lines depicting the associations between residuals of psychological variables and residuals of the logarithms of hair mercury levels with other confounding factors controlled. PCC indicates partial correlation coefficients. Greater hair mercury levels (log values) were significantly associated with (a) lower total intelligence score on the TBIT, (b) lower performance on the Word-Color task, (c) lower performance on the Color-Word task, and (d) lower score on the Beck depression inventory.
