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

Intrathyroidal ectopic thymus (IET) is a benign condition caused by aberrant thymic migration during embryogenesis. Often detected incidentally on ultrasound (US), it can mimic malignant thyroid nodules, leading to unnecessary interventions. We aimed to define the imaging characteristics of IET and emphasize an accurate diagnosis to avoid unwarranted procedures. We describe 5 pediatric cases of IET diagnosed by cervical US and monitored through long-term serial imaging. All lesions appeared as intrathyroidal nodules with echogenicity and internal foci typical of thymic tissue. Follow-up imaging showed no significant changes. None of the patients had thyroid dysfunction or clinical symptoms. The distinctive sonographic features of IET can differentiate it from malignant nodules, preventing unnecessary biopsies or surgeries. US follow-up confirmed a benign course and supports conservative management strategies.
