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

Epidermolysis bullosa (EB), notably severe recessive dystrophic EB (RDEB-S), is associated with increased risk of aggressive mucocutaneous squamous cell carcinomas, the major cause of mortality in early adulthood. This observational, retrospective case review describes a series of EB patients with cutaneous squamous cell carcinomas over a 28-year period. Forty-four EB patients with squamous cell carcinomas were identified with a total of 221 primary tumours. They comprised: 31 (70%) with RDEB-S, 4 (9%) with other RDEB subtypes, 5 (11.4%) with dominant dystrophic EB, 3 (6.8%) with intermediate junctional EB and 1 (2.3%) with Kindler EB. Squamous cell carcinomas occurred earlier in RDEB-S (median age 29.5 years; age range 13-52 years) than other groups collectively (median age 47.1 years; age range 30-89 years) and most had multiple tumours (mean 5.8; range 1-44). Squamous cell carcinoma-associated mortality was high in RDEB-S (64.5%), with median survival after first squamous cell carcinoma of 2.4 years (range 0.5-12.6 years), significantly lower than previous reports, highlighting the need for early surveillance and better treatments.
