gut microbiota alpha/beta diversity
no effect
No significant within-group changes over time or between-group differences or partitions at both V0 and V2 were evidenced by alpha or beta diversity analysis, respectively.
PMID:37307528 · one of two readings recorded this
serum creatinine concentration
no effect
The serum creatinine concentration did not differ significantly after a year, after two and three years in group I and separately in group II (Tables 2 and 3) compared to the baseline values.

estimated glomerular filtration rate (CKD-EPI creatinine equation), percentage change from baseline after 3 years
decreases, -5.56% (omeprazole plus tacrolimus group) vs 9.13% (famotidine plus tacrolimus group), p = 0.0343, p = 0.0343
Not recorded as a finding: the comparison was against another active treatment
However, there was a significant difference between percentage variation of GFR after 3 years of the study (− 5.56% (− 17.24 to 0.00%) vs 9.13% (4.49 to 16.62%), p = 0.0343) (Table 4).

However, there was a significant difference between percentage variation of GFR after 3 years of the study (− 5.56% (− 17.24 to 0.00%) vs 9.13% (4.49 to 16.62%), p = 0.0343) (Table 4).

percentage change in eGFR (CKD-EPI) at 3 years, omeprazole group vs famotidine group
-5.56% (Group I, omeprazole) vs 9.13% (Group II, famotidine), p = 0.0343, p = 0.0343, n = 18
Not recorded as a finding: Comparator is famotidine, an active agent, not absence of omeprazole -- no placebo or no-drug arm exists for this between-group contrast, so it cannot become an outcome edge even though a node (egfr) exists.

mouthfeel aversiveness, 0-100mm VAS
no effect
There were no statistically significant differences in mouthfeel between the samples in pairwise comparisons, while for smell, only the menthol/lemon-flavored 20-mg/mL oral solution (sample 447) had a less aversive smell than the unflavored compounded suspension (p = 0.003).
