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

Necrotizing fasciitis (NF) is a rapidly progressive and life-threatening soft tissue infection. Although it is known to occur in immunocompromised patients, NF following a single dose of chemotherapy has rarely been reported. We describe a 53-year-old woman with hormone receptor-positive, HER2-negative breast cancer and newly diagnosed type 2 diabetes mellitus who developed NF eight days after receiving her first cycle of dose-dense doxorubicin and cyclophosphamide. Initially mistaken for a drug eruption, her condition deteriorated rapidly despite surgical intervention and intensive care. She died of septic shock, and Group G Streptococcus was identified from blood cultures. This case highlights the need to consider NF in post-chemotherapy patients presenting with erythema and systemic symptoms, even after a single dose, particularly when risk factors such as diabetes and obesity are present. Prompt recognition and intervention remain essential to improve survival.
