Beyond Lymphovascular Invasion: Site-Dependent Patterns of Lymphatic, Venous and Perineural Involvement in Laryngo-Hypopharyngeal Carcinoma.

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
backgroundBuilding on our recent characterization of a layer-specific neurovascular microenvironment in the normal human vocal fold, we examined how that unit behaves in laryngo-hypopharyngeal carcinoma, where lymphatic and venous involvement are conventionally reported together.
methodsWe retrospectively analyzed 48 laryngo-hypopharyngeal squamous cell carcinomas (2017-2025) with complete TNM vascular reporting, confirmed by CD31 and neuron-specific enolase (NSE) immunohistochemistry. Lymphatic (L) versus venous (V) assignment rested on morphological criteria, since CD31 cannot discriminate lymphatic from blood vessels and D2-40 was unavailable. L, V and perineural (Pn) status were related to pT stage and topography and combined into a composite score (NV = L + V + Pn), reassessed after adjustment for pT.
resultsConcordant patterns predominated (L0V0 60.4%, L1V1 27.1%); 12.5% were dissociated. Vascular invasion correlated with pT (ρ = 0.393,
conclusionsReporting L, V and Pn separately-parameters already in routine TNM notation-may capture tumor aggressiveness more completely than LVI as a single entity. This series cannot establish stage-independent co-variation in these axes, validate the L/V distinction molecularly, or, lacking follow-up, demonstrate prognostic value.
