Polar plot of ∆CO expressed as polar coordinates (radius and polar angle). The central grey circle represents the exclusion zone (mean ∆CO < 10%). The black dashed line represents the mean polar angle of 3.9° (mean angular bias), light gray dashed lines represent the radial LoA (± 12.1°). Sixteen data points were excluded from analysis because they fell in the exclusion zone
