Utility of solid area diameter in management of cystic papillary thyroid carcinoma.
Article in Endocrine connections, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Papillary thyroid carcinoma (PTC) with marked cystic formation (CPTC) is not a subtype of PTC, and its clinical characteristics have not been fully investigated. This study aimed to clarify the clinical and pathological characteristics of CPTC and propose important indicators for its clinical management. Thirty-three CPTC nodules with cystic areas occupying >50% of their volume were examined. Two matched controls (MCs) were prepared, one with tumor diameter matched for whole tumor diameter (WTD) of CPTCs and the other with tumor diameter matched for solid area diameter (SAD) of CPTCs. The mean age of patients with CPTC was 55.2 years significantly older than that in SAD-MCs. Of the CPTCs, 69.7% were classified as highly suspicious by ultrasonography, and the prevalence was lower than that in WTD-MCs (88.9%) and SAD-MCs (91.5%). Total thyroidectomy was performed in 69.7% of CPTC cases, which was significantly less frequent than that in WDT-MCs (91.7%) and similar to that in SAD-MCs (76.1%). Histologically, CPTCs exhibited two characteristic findings: invasion from the solid area into the surrounding normal thyroid tissue and granulation tissue around the cystic wall. The frequencies of the cases with pathological lateral node metastasis, extrathyroidal extension, and Ki-67 labeling index ≥5% in CPTCs were significantly lower than those in WTD-MCs and relatively similar to those in SAD-MCs. In the surgical strategy and prognosis of CPTC, the evaluation of tumor size should be based on SAD rather than on WTD. We advocate measuring not only WTD but also SAD in CPTC.
