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

Inactivation of the tumor suppressor adenomatous polyposis coli, with the resultant activation of beta-catenin, is the initiating event in the development of a majority of colorectal cancers. Krüppel-like factor 5 (KLF5), a proproliferative transcription factor, is highly expressed in the proliferating intestinal crypt epithelial cells. To determine whether KLF5 contributes to intestinal adenoma formation, we examined tumor burdens in Apc(Min/+) mice and Apc(Min/+)/Klf5(+/-) mice. Compared with Apc(Min/+) mice, Apc(Min/+)/Klf5(+/-) mice had a 96% reduction in the number of intestinal adenomas. Reduced tumorigenicity in the Apc(Min/+)/Klf5(+/-) mice correlated with reduced levels and nuclear localization of beta-catenin as well as reduced expression of two beta-catenin targets, cyclin D1 and c-Myc. In vitro studies revealed a physical interaction between KLF5 and beta-catenin that enhanced the nuclear localization and transcriptional activity of beta-catenin. Thus, KLF5 is necessary for the tumor-initiating activity of beta-catenin during intestinal adenoma formation in Apc(Min/+) mice, and reduced expression of KLF5 offsets the tumor-initiating activity of the Apc(Min) mutation by reducing the nuclear localization and activity of beta-catenin.
