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

Colorectal cancer (CRC) remains a leading cause of cancer mortality worldwide. Regulatory T cells (Tregs) are key immune regulators that inhibit anti-tumor immune responses by suppressing effector T-cell functions and fostering an immunosuppressive tumor microenvironment. Despite epidemiological evidence showing an inverse association between milk consumption and CRC risk, the underlying mechanisms remain unclear. While milk-derived fatty acids have demonstrated tumor-suppressive activities, the anti-tumor effects of hexanoic acid, a characteristic component of milk fat, have not been thoroughly investigated. Model tumor mice orally administered hexanoate, the sodium salt of hexanoic acid, showed increased hexanoic acid concentrations in tumor-draining lymph nodes and tumor sites, with enhanced anti-tumor immune responses that significantly suppressed cancer cell growth. These effects were mediated through the following: (1) suppressed differentiation of naïve CD4
