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

backgroundPostoperative chemoradiotherapy (CRT) is a standard therapy for patients with high-risk factors for head and neck squamous cell carcinoma, including positive margin and extra-nodal extension (ENE). However, the prognostic impact of the number of pathological metastatic lymph nodes (pLNs) in hypopharyngeal carcinoma (HPC) is unclear. Thus, this study aimed to investigate postoperative prognostic factors for locally advanced hypopharyngeal squamous cell carcinoma (LA-HPSCC) with a focus on the number of pLNs.

methodsWe retrospectively analyzed medical records of 99 consecutive patients with LA-HPSCC who underwent total pharyngo-laryngo-esophagectomy (TPLE) and bilateral neck dissection (ND) between December 2002 and May 2019.

resultsThe median follow-up time for all censored patients was 63.2 months. The median overall survival (OS) was 101.0 months (95% confidence interval [CI] 48.1-134.9). patients had pLNs ≥ 3. Forty-six (45.5%) patients were diagnosed with ENE. Twenty (20.2%) patients received postoperative CRT. The multivariate analysis revealed that pLNs ≥ 3 (median OS: 163.2 vs. 31.8 months, hazard ratio [HR] 2.39, 95% CI 1.16-4.94, p < 0.01) and ENE (median OS: 161.0 vs. 26.3 months, HR 4.60, 95% CI 2.26-9.36, p < 0.01) were significantly associated with poor prognosis and that postoperative CRT (HR 0.34, 95% CI 0.16-0.72, p < 0.01) was significantly associated with better prognosis. The cumulative incidence of distant metastasis was higher in patients with pLNs ≥ 3 than in those with pLNs < 3 (p < 0.01).

conclusionpLNs ≥ 3 and ENE were significant poor prognostic factors for patients with LA-HPSCC who underwent TPLE and bilateral ND.
