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
This study examines the clinicopathological characteristics of patients with coexistent medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC). A retrospective analysis was conducted on 169 patients who underwent surgical treatment for MTC at 2 medical centers between 2010 and 2019. The clinicopathological characteristics were documented, and associations between MTC/PTC and MTC were evaluated. Among the 169 MTC patients, 16 (9.5%) exhibited concomitant histological characteristics of both MTC and PTC. Three patterns of carcinoma distribution were identified: mixed carcinoma, tumors confined to the ipsilateral glandular lobe, and MTC/PTC lesions dispersed across both glandular lobes. Of these 16 patients, 9 were female and 7 were male, with a mean age of 50.6 years. The PTC lesions had a maximum diameter of 0.40 ± 0.21 cm, whereas the MTC lesions measured 1.73 ± 1.86 cm in maximum diameter. Additionally, 9 cases exhibited lymph node metastases, but no distant metastases were observed. Univariate analysis indicated no significant associations between MTC/PTC and MTC (P > .05), with no differences in survival or prognosis between the groups.
