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

backgroundReflux symptoms including various extra-esophageal manifestations are commonly reported after esophagectomy. However, the intensity and presentation of reflux are both diverse and variable by patients. In this study we assessed reflux symptoms using the reflux symptom index (RSI) questionnaire in patients who underwent esophagectomy for esophageal cancer to order to identify the prevalence of significant reflux and its risk factors.

methodsFrom April 2017 to July 2017, we investigated patients who underwent esophagectomy for esophageal cancer. The severity of reflux was evaluated with a self-administered nine-item outcomes instrument (score: 0 to 5). An RSI score ≥13 was considered significant reflux. Multivariable analysis was conducted to identify risk factors.

resultsA total of 151 patients was included (mean age, 64.1±8.8 years; male, n=136, 90.1%). The median time after esophagectomy was 22.6 months. The question regarding heartburn, chest pain, indigestion, or acid coming up was most frequently responded (n=104, 68.9%) with 41 (27.2%) patients presenting significant reflux (mean RSI score, 19.9±6.3). Time after esophagectomy <2 years, vocal cord palsy, retrosternal route of reconstruction, and postoperative weight loss were identified as significant risk factors for RSI ≥13 in the multi-variable analysis.

conclusionsReflux related symptoms including extra-esophageal manifestations were common. Our study revealed that short duration after esophagectomy, vocal cord palsy, retrosternal route of reconstruction, and postoperative weight loss were significant associated factors for reflux symptom after esophagectomy.
