An Investigation of the Significance of Residual Confounding Effect

Table 2

Source and magnitude of bias in replicate 1.

Confounder/; Component	Correlation with exposure^1	Percentage of misclassification^2
𝑋17	0.183	13.4%
𝑋50	0.160	14.4%
𝑋7	0.135	26.7%
𝑋29	0.150	15.5%
𝑋53	0.181	11.6%
𝑋18	0.227	5.89%
𝑋20	0.155	10.8%
𝑋21	0.292	31.2%
𝑋38	0.188	7.9%
𝑋91	0.282	11.4%

1Measured as the correlation coefficient between binary form of component (occurred or not occurred) and binary from of exposure in the 50,000 observations for replicate 1.
²Measured as 1 minus the proportion of correct classification of confounder/component status (occurred or not occurred) in the 50,000 observations for replicate 1.
