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

aimsTo examine possible effects of polymorphism in the SLCO1B1 gene, encoding the hepatic uptake transporter organic anion transporting polypeptide (OATP) 1B1, on the pharmacokinetics of rosiglitazone and pioglitazone in a prospective genotype panel study.

methodsSixteen healthy volunteers with the homozygous SLCO1B1 c.521TT genotype (controls), 12 with the heterozygous c.521TC genotype and four with the homozygous c.521CC genotype ingested a single 4-mg dose of rosiglitazone and a single 15-mg dose of pioglitazone in a cross-over study with a wash-out period of at least 1 week.

resultsSLCO1B1 polymorphism had no statistically significant effect on any of the pharmacokinetic variables of rosiglitazone, pioglitazone or their metabolites. The mean +/- SD area under the plasma rosiglitazone concentration-time curve from time 0 to infinity (AUC(0-infinity)) was 2024 +/- 561 ng ml(-1) h in the c.521TT subjects, 1763 +/- 288 ng ml(-1) h in the c.521TC subjects (geometric mean ratio c.521TC/c.521TT 0.89; 95% confidence interval 0.72, 1.11) and 1729 +/- 346 ng ml(-1) h in the c.521CC subjects (c.521CC/c.521TT 0.87; 0.63, 1.20). The AUC(0-infinity) of pioglitazone averaged 6244 +/- 1909 ng ml(-1) h in the c.521TT subjects, 5123 +/- 1165 ng ml(-1) h in the c.521TC subjects (c.521TC/c.521TT 0.83; 0.65, 1.06) and 4851 +/- 1123 ng ml(-1) h in the c.521CC subjects (c.521CC/c.521TT 0.79; 0.55, 1.14). There was a significant correlation between the AUC(0-infinity) of rosiglitazone and pioglitazone (r = 0.717, P < 0.001).

conclusionsThe SLCO1B1 c.521T-->C SNP does not affect the pharmacokinetics of rosiglitazone or pioglitazone, indicating that OATP1B1 plays no significant role in the disposition of these drugs.
