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

Factitious thyrotoxicosis (FTT) from exogenous thyroid hormone ingestion is an uncommon cause of thyrotoxicosis requiring distinct management from endogenous causes. We report a 19-year-old male patient who developed thyrotoxicosis after consuming raw bovine thyroid purchased online. Laboratory evaluation revealed suppressed thyroid-stimulating hormone, elevated free thyroxine hormone levels, and normal thyroglobulin levels with negative anti-thyroid antibodies and normal thyroid ultrasonography, strongly supporting the diagnosis. The patient was successfully managed with supportive care, and thyroid hormone levels trended downward during hospitalization. Clinicians should obtain detailed dietary and supplement histories when evaluating thyrotoxicosis, as emerging online health trends may promote the consumption of various unusual items such as raw animal organs. Suppressed thyroglobulin is a key diagnostic marker distinguishing FTT from endogenous causes.
