Prognostic Significance of Lymph Node Parameters in Laryngeal Cancer After Laryngectomy.

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
objectiveThe aim of this study was to evaluate the prognostic significance of lymph node yield, lymph node positivity ratio, and metastatic lymph node count in patients with laryngeal cancer undergoing laryngectomy with neck dissection, and to identify optimal cutoff values for these parameters using receiver operating characteristic (ROC) curve analysis.
methodsThis retrospective study included 48 patients who underwent partial or total laryngectomy with bilateral neck dissection at a tertiary referral center between January 2015 and December 2019. Demographic characteristics, TNM stage, lymph node parameters, pathological risk factors, recurrence, and mortality were analyzed. Neck dissection primarily bilateral involved cervical levels II-IV, with additional levels dissected when clinically or radiologically indicated.
resultsMetastatic lymph node count was significantly associated with overall survival in both univariate and multivariable Cox analyses (HR: 1.344, p < 0.001; HR: 1.348, p = 0.007, respectively). An optimal lymph node ratio (LNR) cutoff of 0.045 was identified. LNR ≥ 0.045 was associated with poorer survival (log-rank p = 0.006) and increased mortality in univariate analysis (HR: 4.815; p = 0.013), but not in multivariable analysis (p = 0.325).
conclusionsIn conclusion, the findings of this study demonstrate that lymph node-based parameters are important prognostic indicators in laryngeal cancer. Among these, the absolute number of metastatic lymph nodes emerged as the most robust and biologically meaningful predictor of overall survival. LEVEL OF EVIDENCE: 3:
