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

objectiveTo study the effects of CYP2C9 and CYP2C19 genetic polymorphisms on the pharmacokinetics and pharmacodynamics of glipizide.

methodsEighteen healthy male subjects were divided into three groups according to their genotypes: group I, CYP2C9*1/*1 and CYP2C19 extensive metabolizers (EMs); group II, CYP2C9*1/*1 and CYP2C19 poor metabolizers (PMs); and group III, CYP2C9*1/*3 and CYP2C19 EMs. After a single dose of a 5-mg glipizide tablet, plasma concentrations of glipizide for a 36-h period were determined. Meanwhile, plasma glucose levels and plasma insulin levels were determined from 0 to 4 h after dosing.

resultsThe area under the plasma concentration-time curve (AUC(0-infinity)) was 2.0-fold higher and the oral clearance was 51.1% lower in group III than in group I. The change in fasting insulin level within 1 h (DeltaAUEC(insulin0-1h)) in group III was 3.8-fold higher than that in group I. The glipizide parameters in group II exhibited similar tendencies to those in group III.

conclusionsThese results suggest that CYP2C9 polymorphism significantly influences the pharmacokinetics and pharmacodynamics of glipizide, which needs to be considered in clinical practice. CYP2C19 polymorphism exhibits a tendency to influence the effects of glipizide, to a certain extent similarly to CYP2C9 polymorphism.
