Impact of Close Margins on Oral Cancer Outcomes According to the Oral Subsite.
Article in Head & neck, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses that pooled 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.
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
backgroundThe prognostic significance of close margins in oral squamous cell carcinoma (OSCC) is controversial. We wished to investigate the impact of close margins on the risk of local recurrence (LR) in OSCC according to the oral subsite.
methodsA retrospective cohort study of 342 OSCC patients undergoing primary surgical treatment was conducted. Surgical margins were based on the main specimen and defined as positive (SCC at margins), close (< 5 mm), or clear (≥ 5 mm).
resultsAmong tongue SCC cases, both positive (hazard ratio 13.48, 95% CI 2.03, 32.91) and close margins (hazard ratio 3.87, 95% CI 1.31, 11.34) were significantly associated with LR. Tongue margins < 4 mm were associated with higher LR. Among non-tongue SCC cases, only positive margins (hazard ratio 4.10, 95% CI 1.19, 14.21) were associated with LR. Close margins were not significant (hazard ratio 1.59, 95% CI 0.46, 5.42).
conclusionsClose margins appear to have a differential impact on LR in OSCC according to the oral subsite.
