The increased risk allele that associates with a lower urinary Ca is depicted as superscript when P ≤ 0.001 and MAF is higher than 0.10. Letters in superscript depict the nucleotides that are associated with a lower urinary excretion of Ca (^A, Adenine; ^T, thymine). HWE, Hardy-Weinberg equilibrium; MAF, minor allele frequency; uCa, urinary Ca. 

^aEstimable size effect due to MAF was less than 0.05 and lack of variability.
