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

backgroundGene polymorphisms of the UDP-glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) contribute to individual variations in adverse events among patients administered irinotecan, and the distribution of the polymorphisms shows large interethnic differences. Variation in the solute carrier organic anion-transporter family, member 1B1 (SLCO1B1) gene also has a significant effect on the disposition of irinotecan in Asian cancer patients. In the present study, we evaluated the association of genetic polymorphisms of UGT1A1 and SLCO1B1 with irinotecanrelated neutropenia in Japanese cancer patients.

methodsOne hundred and thirty-five consecutive patients treated with irinotecan were enrolled. Genotypes of UGT1A1 (*60, *28, *6, and *27) and SLCO1B1 (*1b, *5, and haplotype *15) were determined by direct sequencing. Severe neutropenia refers to events observed during the first cycle of irinotecan treatment.

resultsSevere neutropenia was observed in 29 patients (22%). Six patients were homozygous and 48 heterozygous for UGT1A1*6. Only 1 patient was homozygous for UGT1A1*28. Homozygosity for UGT1A1*6 was associated with a high risk of severe neutropenia (odds ratio [OR], 7.78; 95% confidence interval [CI], 1.36 to 44.51). No significant association was found between severe neutropenia and other UGT1A1 polymorphisms or SLCO1B1 polymorphisms.

conclusionThese findings suggest that the UGT1A1*6 polymorphism is a potential predictor of severe neutropenia caused by irinotecan in Japanese cancer patients.
