1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeTo assess the influence of the P450 oxidoreductase 28 SNP (POR 28) on tacrolimus pharmacokinetics in the Chinese population.

methodsSeventy-one healthy Chinese volunteers enrolled in the study received an oral dose of 2 mg of tacrolimus after providing written informed consent. CYP3A5 3 was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and POR*28 was genotyped by PCR-direct sequencing. Tacrolimus whole blood concentrations were determined by ultra performance liquid chromatography-tandem mass spectrometry and the pharmacokinetics analyses was evaluated by nonparametric methods.

resultsThe frequencies of CYP3A5 3 and POR 28 allele were 73.3 % and 29.6 %, respectively. No significant differences existed in tacrolimus pharmacokinetics between the POR 28 CC homozygotes (n = 32) and the POR 28 T allele (n = 39) in all subjects. The mean tacrolimus AUC0-24, AUC0-∞ and Cmax for the POR 28 CC (n = 14) homozygotes in CYP3A5 expressers (CYP3A5 1/ 1 or 1/ 3 genotype) were 71.5 ± 38.9 h ng/mL, 94.3 ± 58.3 h ng/mL and 17.6 ± 9.8 ng/mL, which were much higher than the POR 28 CT heterozygotes (n = 17) of 46.7 ± 24.9 h ng/mL, 57.4 ± 33.9 h ng/mL and 11.2 ± 6.4 ng/mL (P < 0.05, respectively). We did not observe any significant differences in tacrolimus pharmacokinetics between the POR 28 CC homozygotes (n = 18) and POR 28 T carriers (n = 22) in CYP3A5 nonexpressers (CYP3A5 3/ 3 carriers).

conclusionsThe POR 28 CT genotype presented a significantly lower level of tacrolimus exposure (AUC, Cmax) compared with the POR 28 CC genotype in CYP3A5-expressing subjects. It suggested that the POR 28 genetic polymorphism might also be responsible for the marked interindividual variability of tacrolimus besides the CYP3A5 3 genetic polymorphism.
