Comparison of linear relationships between circulating CRP and residual BMI observationally and when estimated employing FTO loci as an instrument for residual BMI.

X and Y axes represent residual BMI and CRP respectively.

Light blue points represent a scatter plot of the correlation between circulating CRP and residual BMI.

Grey areas represents 95% confidence regions around instrumental variables estimates.

Black area represents 95% confidence regions around simple linear regression estimates.

(The 50 individuals with extreme residual BMI over 20 kg/m2 are not shown on the plot but were included in the analyses that gave the fitted lines and confidence regions.)
