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

purposeThe purpose of this study was to clarify the clinical features and outcomes of patients with recurrence after esophagectomy following neoadjuvant chemotherapy (NAC) related to the timing of recurrence.

methodsWe reviewed 240 consecutive patients who underwent NAC followed by esophagectomy for clinical stage II/III esophageal squamous cell carcinoma between 2009 and 2014. We compared the clinical features and survival after recurrence among groups of patients stratified by the timing of recurrence diagnosis and identified the risk factors for early recurrence (ER).

resultsRecurrence was identified within 1 year in 61 patients and after 1 year in 23 patients. Significant differences were observed between the patients with recurrence within 1 year (early recurrence; ER) and those with recurrence after 1 year (late recurrence; LR). The ER patients had more advanced tumors and higher pretreatment serum squamous cell antigen (SCC-Ag) levels and less experienced downstaging than patients without recurrence (no recurrence; NR). Overall survival was significantly worse for the ER patients than for the LR patients. Multivariate analysis revealed that cN2-3, increased serum SCC-Ag levels, and clinical response to NAC were independent predictors of ER.

conclusionThe ER patients had distinctive clinical features from the LR and NR patients. Extensive lymph node metastasis, an elevated SCC-Ag, and inadequate response to NAC were identified as predictors of ER.
