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

The serrated neoplasia pathway accounts for approximately 20% of colorectal carcinomas (CRCs). Sessile serrated adenomas (SSAs), the main precursor lesion of the serrated pathway, are molecularly driven by MLH1 promoter methylation and microsatellite instability (MSI) in their progression to CRC. MSI-high (MSI-H) lesions are highly immunogenic and associated with a high density of tumor-infiltrating lymphocytes. Our study's aim was to determine how the kinetics of this immune environment relates to SSAs in their progression through low-grade (SSA-LD) to high-grade dysplasia (SSA-HD) and CRC. We analyzed 74 cases (16 CRCs, 14 SSAs-HD, and 44 SSAs-LD). Cases of hyperplastic polyp and SSA without dysplasia were analyzed for comparison. MSI status, intraepithelial lymphocyte (IEL) density, and immune checkpoint expression were assessed by immunohistochemistry for mismatch repair proteins, CD3, and PD-1/PD-L1, respectively. Average IEL density was 12, 18.6, 21.6, and 31 for SSA, SSA-LD, SSA-HD, and CRC, respectively, as opposed to 8.1 in normal colon (P < .0001). Average PD-1/PD-L1 lymphocytic expression was 1.1/1.0, 1.2/2.9, 4.8/6.9, and 12.4/15.2 in SSA, SSA-LD, SSA-HD, and CRC, respectively, compared with 0.5/0 in normal crypts (P < .0001). IEL and PD-1/PD-L1 lymphocytic expression values of MSI-H lesions were 22.6, 27.7, and 36.8, and 3/6.5, 6.2/10.6, and 18.3/17.6 in MSI-H SSA-LD, SSA-HD, and CRCs, respectively (P ranged from .0478 to .3529). PD-L1 epithelial expression was positive in 40% of SSAs, 59.1% of SSAs-LD, 100% of SSAs-HD, and 60% of CRCs (P < .0001). Increased IELs and PD-1/PD-L1 expression correlate with sequential progression of SSAs, through development of cytologic dysplasia, to CRC and MSI-H status.
