1 · What the graph read from it

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.

2 · The registry

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

backgroundThe lymph node density (LND) is the number of positive metastatic lymph nodes divided by the total number of dissected lymph nodes. The purpose of this study was to evaluate LND as a prognostic factor in patients with laryngeal squamous cell carcinoma (SCC).

methodsThe study included 186 patients with laryngeal SCC submitted to laryngeal surgical treatment with neck dissection between January 2009 and December 2016. Clinical-pathological variables were assessed, as well as the cut-off point for LND.

resultsLND value was calculated considering pN+ (LND = 0.060). The Kaplan-Meier curve (log-rank) related to cumulative survival demonstrated that patients with LND ≥ 0.060 had a higher mortality rate than those with LND < 0.060, presenting a more aggressive form of the disease, with earlier recurrence. However, only the LND ≥ 0.060 group had impact on both disease-free survival and overall survival.

conclusionThe LND proved to be an important index in the prognostic evaluation of larynx SCC patients having a direct relationship with disease recurrence. Patients with LND ≥ 0.060 should be considered for adjuvant therapy.
