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

Cyclosporine (CsA) is a substrate of cytochrome P450 (CYP) 3A5 and has a narrow therapeutic range with large inter-individual variability. CYP3A5*3 polymorphism is reported to be functional and may contribute to the inter-individual variability. The objective of this meta-analysis was to accurately estimate the effect of CYP3A5*3 allele on CsA dose-adjusted blood concentration. A computerized literature search was conducted in PubMed. A total of 12 and 6 studies meeting the inclusion criteria were, respectively, included in meta-analysis about dose-adjusted trough concentration (C(0)/D) and dose-adjusted peak concentration (C(2)/D). The combined weighted mean difference (WMD) between CYP3A5 expressers (*1/*3 + *1/*1) and non-expressers (*3/*3) was significant in C(2)/D (WMD = -12.73 (ng ml(-1))/(mg kg(-1)), 95% confidence interval (CI) -25.23 to -0.22, P = 0.046), whereas it was marginally significant in C(0)/D (WMD = -3.75 (ng ml(-1))/(mg kg(-1)), 95% CI -7.58 to 0.07, P = 0.054). Exclusion of an outlier study greatly increased the association of CYP3A5 polymorphism with C(0)/D to be significant (WMD = -4.92 (ng ml(-1))/(mg kg(-1)), 95% CI: -8.27 to -1.58, P = 0.011). This meta-analysis showed that CYP3A5*3 polymorphism is associated with CsA dose-adjusted concentration in renal transplant recipients. Patients carrying the CYP3A5*3/*3 genotype will require a lower dose of CsA to reach target levels compared with the CYP3A5*1/*1 or *1/*3 carriers.
