Time course of renal calcium metabolic indices. Open circle: Early-D; closed square: Late-D. (a) filtered calcium load (F-Ca), (b) tubular threshold for calcium (TCa/CCr), (c) urinary calcium excretion per hour (U-Ca/h), (d) renal fractional calcium excretion (FE-Ca). Differences between Early-D and Late-D were calculated using the Student’s t-test for paired comparisons or Wilcoxon signed-rank test. Differences from baseline were calculated using a repeated measure ANOVA or Friedman's Test with Bonferroni post hoc test. Early-D: early dinner; Late-D: late dinner. *P < 0.001, **P < 0.01, ***P < 0.05 Early-D versus Late-D. §P < 0.001, §§P < 0.01 versus baseline for Early-D. †P < 0.001, ††P < 0.01 versus baseline for Late-D
