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

purposeMetastatic lymph node (LN) burden is one of the most important prognosticators in human solid cancers, but has rarely been examined in laryngeal and hypopharyngeal cancers (LHC). We evaluated the nodal factors predictive of recurrence and survival in patients with LHC.

methodsThis study included 141 consecutive patients who underwent primary surgery and neck dissection for previously untreated LHC at our tertiary referral centre. Nodal factors included the presence of pathological LN metastasis, number of positive LNs, LN ratio, and extra-nodal extension (ENE). Our proposed N classification was analysed by recursive partitioning analysis and compared with the AJCC and other N classifications using the c-index. Univariate and multivariate Cox proportional hazard regression analyses were used to define significant predictors of post-treatment disease-free survival (DFS) and overall survival (OS).

resultsOf the 141 patients, 66 (46.8%) had positive LNs, and 27 (19.1%) had ENE. In multivariate analyses, the number of positive LNs was strongly associated with DFS and OS outcomes (P < 0.01). Our new N classification was proposed with four categories, such as N0 (0 LN +), N1 (1 LN +), N2 (2-4 LN + or ENE) and N3 (≥ 5 LN +). The C-index of our new N classification improved the OS prediction (0.718) compared with the AJCC and the other N classifications (0.704-0.713).

conclusionMetastatic LN burden is an important predictor of survival in patients with LHC. A proposed N classification using the number of positive LNs and ENE might improve the LHC survival prediction.
