Ethanol Ablation of Metastatic Lymph Nodes in Patients With Papillary Thyroid Carcinoma-Predictors of Clinical Outcome.

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
contextEthanol ablation (EA) is a treatment option in recurrent or persistent metastatic lymph nodes (MLNs) from papillary thyroid carcinoma.
objectiveThis work aimed to assess whether ultrasonographic characteristics of the MLN, history of lymph node surgery, aggressive histological subtype, or BRAFV600E mutation in the primary tumor predict long-term response from EA.
methodsSeventy-five patients who received EA at a tertiary referral center were included. We evaluated treatment response from the most recent clinically indicated examination, or a study-specific examination. BRAFV600E analysis and review of histological subtypes in the primary tumor were conducted.
resultsMedian interval from initial surgery to follow-up was 119 months (range, 39-471 months). Pure cystic MLN had a better outcome than the solid and partially cystic MLN (13/13, 100% vs 90/121, 74%; P = .039). Small MLNs (≤0.5 mL) had a higher response rate compared to larger lesions (71/92, 77% vs 10/19, 53%; P = .045). We observed no difference in EA response between patients with or without the BRAFV600E mutation (80/99, 81% vs 17/25, 68%; P = .181) or an aggressive subtype (22/24, 92% vs 75/100, 75%; P = .099) in their primary tumors. EA achieved similar rates of locoregional disease control in neck regions with or without previous lymph node surgery (66% vs 63%, P = .825).
conclusionEA was highly effective in pure cystic MLNs. Partially cystic or noncystic MLNs over 0.5 mL were less responsive, though many of these MLNs still showed a lasting response. BRAFV600E mutation, aggressive histological subtype, or absence of prior lymph node surgery did not negatively affect EA response.
