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 impacts of erythromycin on the pharmacokinetics of voriconazole and its association with CYP2C19 genotypes in healthy Chinese male subjects.

methodsA single-center, open, crossover clinical study with two treatment phases was carried out. Eighteen healthy male volunteers, including 6 CYP2C19 homozygous extensive metabolizers (EMs, *1/*1), 6 heterozygous EMs (HEMs, *1/*2 or *1/*3), and 6 CYP2C19 poor metabolizers (PMs, *2/*2 or *2/*3), were enrolled in this study. A single oral dose of 200 mg voriconazole was administrated to all subjects after 3-day pretreatment with either 500 mg erythromycin or placebo three times daily. Periods were separated by a washout period of 14 days. Serial venous blood samples were collected, and plasma concentrations of voriconazole were determined by HPLC.

resultsC(max), AUC(0-24), and AUC(0-infinity) of voriconazole were increased significantly, while oral clearance of voriconazole was decreased significantly by erythromycin administration (p < 0.001, respectively). Compared with individuals with CYP2C19 PM genotypes, individuals with CYP2C19 EM and HEM genotypes showed significantly decreased T(½), AUC(0-24), AUC(0-infinity), and increased oral clearance of voriconazole (p < 0.05, respectively). In addition, significant increases in AUC(0-24) and AUC(0-infinity) and decreases in oral clearance of voriconazole after erythromycin treatment were observed in CYP2C19 HEMs and PMs (p < 0.05, respectively), but not in CYP2C19 EMs.

conclusionBoth CYP2C19 genotypes and CYP3A4 inhibitor erythromycin can influence the plasma concentration of voriconazole, and erythromycin increases plasma concentration of voriconazole in a CYP2C19 genotype-dependent manner.
