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.
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
The small intestine plays a critical role in the absorption and metabolism of orally administered drugs. Therefore, a model capable of evaluating drug absorption and metabolism in the small intestine would be useful for drug discovery. Patients with genotype UGT1A1*6 (exon 1, 211G > A) treated with the antineoplastic drug SN-38 have been reported to exhibit decreased glucuronide conjugation and increased incidence of intestinal toxicity and its severe side effects, including severe diarrhea. To ensure the safety of drugs, we must develop a drug metabolism and toxicity evaluation model which considers UGT1A1*6. In this study, we generated CYP3A4·POR·UGT1A1 KI- and CYP3A4·POR·UGT1A1*6 KI-Caco-2 cells for pharmaceutical research using a PITCh system. The CYP3A4·POR·UGT1A1 KI-Caco-2 cells were shown to express functional CYP3A4 and UGT1A1. The CYP3A4·POR·UGT1A1*6 KI-Caco-2 cells were sensitive to SN-38-induced intestinal toxicity. We thus succeeded in generating CYP3A4·POR·UGT1A1 KI- and CYP3A4·POR·UGT1A1*6 KI-Caco-2 cells, which can be used in pharmaceutical research. We also developed an intestinal epithelial cell model of patients with UGT1A1*6 and showed that it was useful as a tool for drug discovery.
