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) patients are frequently diagnosed with metastases to the peritoneal cavity. These patients have a dismal prognosis and only limited therapeutical benefits. Solid tumors, including CRC, often display elevated levels of sialylated glycan structures, acting as immune checkpoints for immune evasion. However, the detrimental effects of tumor sialylation on antitumor immunity at the peritoneal site remain unexplored. We uncovered that sialylation is higher in peritoneal metastases (PM) compared with primary CRC or liver metastases. Intraperitoneal injection of sialic acid-deficient CT26 CRC cells led to significantly less peritoneal tumor development and a lower peritoneal cancer index (PCI) score. Sialic acid-devoid tumors harbored higher numbers of live CD45
