The Significance of Transcapsular Blood Flow for Assessing Moderate to Severe Extrathyroidal Extension: Results of a Two-Center Study.
Article in International journal of general medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundExtrathyroidal extension (ETE) is a crucial factor affecting the prognosis of thyroid cancer. Two-dimensional ultrasound is highly sensitive to ETE, but the sensitivity and specificity for severe ETE are unideal, so it does not improve the prognosis. MATERIALS AND
methodsThis retrospective study evaluated patients within three years of subcapsular thyroid cancer diagnosis with fine-needle aspiration (FNA). Routine ultrasound was performed and examined before surgery. In addition to the traditional two-dimensional assessment method, particular attention was paid to transcapsular blood vessels, and the diagnostic efficacy of the two methods for mild, severe, and anterior and posterior ETE was compared.
resultsA total of 208 thyroid cancer nodules were included. Tumor size and gender were correlated with whether ETE occurred. The general method is more accurate for the overall identification of ETE but is not specific enough for severe ETE, while the transvascular method is the opposite. The two are similar in identifying the ETE of the anterior capsule, but the transvascular method has higher specificity in identifying the ETE of the posterior capsule.
conclusionThe traditional two-dimensional method is highly sensitive to ETE detection in the anterior capsule, while transcapsular blood flow can more effectively detect extensive ETE and ETE in the posterior capsule.
