Survival Impact of Lingual Lymph Node Metastases in Tongue Cancer: An Analysis Regarding Anatomical Subsites.
Article in In vivo (Athens, Greece). 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
BACKGROUND/
aimLingual lymph node (LLN) metastasis from tongue cancer occurs at four subsites. However, subsite-related prognosis is unknown. This study aimed to analyze the association between LLN metastases and disease-specific survival (DSS) with respect to these four anatomic subsites. PATIENTS AND
methodsPatients with tongue cancer treated between January 2010 and April 2018 at our institute were reviewed. The four subgroups of LLNs were median, anterior lateral, posterior lateral, and parahyoid. DSS was evaluated.
resultsLLN metastases occurred in 16 of the 128 cases; six and 10 cases were identified during initial and salvage therapy, respectively. Zero, four, three, and nine cases were median, anterior lateral, posterior lateral, and parahyoid LLN metastases, respectively. The 5-year DSS of patients with LLN metastasis was significantly poor on univariate analysis; parahyoid LLN metastasis showed the worst prognosis. Multivariate analysis indicated that only advanced nodal stage and lymphovascular invasion were significant survival factors.
conclusionParahyoid LLNs may require the most caution in tongue cancer. The significance of LLN metastases alone for survival was not confirmed on multivariate analysis.
