A nonsignificant trend toward elevated iPTH was noted in the bicarbonate group (SMD, 0.80; 95% CI, −0.04 to 1.64; P = 0.06, I 2 =84.82%) ( Supplemental Figure 6C ).

In the subgroup analyses across stages 3b and 4 of CKD and different eGFR equations, the interaction effect did not reach statistical significance, with P values of 0.19 and 1, respectively.
