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

aimsDirect tumour-adipocyte interaction at the invasion front, termed Stroma AReactive Invasion Front Areas (SARIFA), has recently emerged as a novel H&E-based biomarker in colorectal cancer (CRC). SARIFA positivity is defined by a direct tumour-adipocyte contact (TAC) without intervening stroma or inflammatory infiltrate. We performed a focused evidence synthesis of all published studies and a meta-analysis to summarize the evidence on the prognostic value of TAC/SARIFA in CRC. METHODS AND

resultsEligible studies, identified via PubMed (7 May 2026), were observational cohorts reporting multivariable-adjusted hazard ratios (HRs) for TAC/SARIFA positivity vs negativity, with cancer-specific survival (CSS) and overall survival (OS) as endpoints. All included studies were retrospective in design. Study quality was assessed using the Newcastle-Ottawa Scale (NOS). Adjusted HRs were pooled using random-effects meta-analysis with restricted maximum-likelihood estimation and Hartung-Knapp confidence intervals. Of 17 records identified, 12 CRC-focused original publications were included in the qualitative synthesis. Seven cohorts (5,932 patients) contributed CSS and five cohorts (4,545 patients) OS data, drawn from eight independent cohorts across six studies. All studies were rated good quality (NOS 7-9/9). TAC/SARIFA positivity was associated with inferior CSS (pooled HR 1.77, 95% confidence interval [CI] 1.55-2.01) and OS (pooled HR 1.53, 95% CI 1.39-1.68), with no relevant heterogeneity detected.

conclusionTAC/SARIFA positivity is independently associated with inferior CSS and OS in CRC, warranting prospective validation. We propose TAC as a more descriptive terminology.
