Data are shown as median (IQR). HBS = high bicarbonate and sodium, LBS = low bicarbonate and sodium. PRAL = potential renal acid load. ∗Time × group interactions were analyzed using two-way repeated measures ANOVA. ∗∗Differences between t0 and t28 within each group were analyzed using paired t-Test and Wilcoxon-Test. The bold values are significant at p <0.05.
