Predicting Structural Progression-Free Survival After Surgery for Medullary Thyroid Carcinoma.
Observational study in World journal of surgery, 2026. 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
introductionMedullary thyroid cancer (MTC) is an aggressive tumor for which surgery is the only curative treatment. However, after surgery, some patients may experience persistence/recurrence. It is important to identify the prognostic factors that may affect structural disease-free survival (SDFS), which may influence the follow-up of our patients.
objectiveTo assess SDFS in patients with MTC and related factors.
methodsA retrospective observational study was conducted in a tertiary hospital including patients with MTC without distant metastases. The following variables were assessed: sex, age, heritability, type of surgery, calcitonin (Ct) and CEA, tumor size, stage, lymph nodes ratio (LNR), vascular invasion, high risk, structural disease, and SDFS. A descriptive and comparative univariate and multivariate analysis of SDFS was performed using SPSS version.29 and Cox regression, defining structural disease as the event. p < 0.05 was considered statistically significant.
resultsA total of 140 patients with a median age of 34 years were evaluated. Forty-six percent (n = 65) were male. Twenty-two percent (n = 31) had sporadic MTC, 75% (n = 106) had MEN2a, and 2% (n = 3) had MEN2b. The median calcitonin level was 182.5pg/mL and median follow-up was 179.5 months. Structural disease occurred in 24% of patients (n = 33). The variables that influenced the SDFS were as follows: sporadic CMT, older age, preoperative CEA, size, lymph node involvement, higher LNR, vascular invasion and high risk, and Ct levels > 150pg/mL at 6-12 months. In the multivariate analysis, age, LNR, T category, and postoperative Ct remained independent predictors.
conclusionThe SDFS in MTC is significantly influenced by LNR, T category, and postoperative Ct levels at 6-12 months.
