a: Funnel plot under the fixed effects model, with contours for the different levels of statistical significance, for the included sample of studies, demonstrating the absence of substantial publication bias due to adequate symmetry around the overall estimate of the petoOR. b: Radial plot under the fixed effects model, demonstrating the absence of significant deviation of our studies’ regression line (dashed line through the origin) from the included regression line for the Egger’s test (solid line)
