Table 2 Significance areas for covariates in the MUR model for the anthropometric variables (N = 38,868) of the model for the right kidney. The total area has been split into areas of positive, negative, and total associations. The standardised regression coefficients (\(\widehat{\beta }\)) are presented as median (interquartile range—IQR) across all vertices of the left kidney surface and the significance areas as a percentage (%) of the vertices with statistically significant associations
