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

objective/hypothesisTo examine the clinical features of benign intratracheal thyroid (ITT) and their management strategies and outcomes. STUDY

designCase series study.

methodsThis systemic review was conducted in two international academic centers. This review includes 43 patients: one new case from the Massachusetts Eye and Ear Infirmary, four new cases from Beijing Tongren Hospital, and 38 previously published cases. We analyzed these 43 cases and summarized the patients' epidemiological data, clinical features, and treatment regimens.

resultsITTs were less common in men than in women (male:female ratio of 3:10). ITT was observed in patients as young as neonates and as old as 85 years. Orthotopic thyroid nodules were present in 55.8% of the patients with ITT. Malignancy was incidentally found in 4.6% of all ITTs. Imaging examinations showed that the ITTs were typically attached to the posterolateral/lateral tracheal wall of the first, second, or third tracheal rings. Tissue attachment between the ITT and normal thyroid lobes was seen in 59.5% of the patients. Thirty-seven patients underwent surgery: 30 underwent open surgery, and seven underwent endoscopic debulking resections. One neonate received thyroid suppression therapy. One patient with ITT and papillary thyroid cancer was treated with radiotherapy and ultimately died after recurrence.

conclusionsSurgical resection is an effective treatment for benign ITT. We hypothesized that abnormalities during the embryonic development of Berry's ligament might play a role in ITT pathogenesis. LEVEL OF EVIDENCE: NA Laryngoscope, 131:E2609-E2617, 2021.
