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

Intentional or accidental injection of mercury into soft tissue is rare. Mercury toxicity typically arises from ingestion or inhalation with instances of subcutaneous injection documented in a limited number of case studies. Most reported cases involve either accidental exposure or deliberate acts, often presenting as painful granulomas, with systemic symptoms a rarity. We present a compelling case involving a 39-year-old woman who developed a localized, painful gluteal lesion filled with mercury following multiple injections of what were purported to be multivitamin ampoules, administered by her ex-husband, a healthcare professional. Remarkably, the patient exhibited a serum mercury level of 345 μg/L without significant systemic manifestations which decreased after a course of treatment with succimer. This report highlights one of the rarest, if not the only documented instance of mercury toxicity caused by subcutaneous injection, potentially with homicidal intent.
