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

Most cases of squamous cell carcinoma (SCC) in pinnipeds are diagnosed postmortem; antemortem diagnosis and active therapeutic intervention are rarely reported, and prognosis is generally considered poor. We report an antemortem diagnosis of mandibular oral SCC in a spotted seal (Phoca largha) with progressive feeding difficulty due to tumor-associated pain that worsened despite analgesics. Partial rostral mandibulectomy (left second incisor to right second premolar) with lip-tissue reconstruction restored feeding by postoperative day 2. Despite tumor recurrence, the seal maintained feeding function and good quality of life for approximately 18 months. This first reported mandibulectomy in a pinniped suggests that surgery may be a valuable palliative option for oral SCC.
