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

purposeEsophagectomy for cancer is an extensive procedure often followed by severe complications. This study investigated whether patients with severe symptoms of reflux are more likely to have sleep disturbances and reduced health-related quality of life (HRQL) after esophagectomy.

methodsThis Swedish nationwide prospective cohort study encompassed all patients who had undergone esophagectomy for cancer between 2013 and 2018. One year after surgery, the patients responded to three questionnaires on reflux (EORTC QLQOG25), sleep disturbances (KSQ), and HRQL (EORTC QLQ-C30). Multivariable logistic regression provided odds ratios (OR) with 95% confidence intervals (CI) for sleep disturbance/reduced HRQL between patients with and without reflux, adjusted for potential confounders.

resultsAmong 241 esophagectomy patients, 66 (27%) reported severe reflux. Patients with reflux had an increased risk of sleep disturbances (OR 2.3, 95% CI: 1.3-4.3) compared to patients without reflux. More specifically, these patients were more likely to suffer from poor sleep quality (OR 4.9, 95% CI: 1.9-12.4). Patients with reflux and sleep disturbances reported reductions in global quality of life, role function, emotional function, social function, and more symptoms in all scales, except for dyspnea.

conclusionsThis study suggests that patients with severe symptoms of reflux after esophagectomy have an increased risk of sleep disturbances and poor sleep quality, which in turn are associated with reduced HRQL. IMPLICATIONS FOR CANCER SURVIVORS: Alleviating reflux after oesophageal cancer surgery is important, since this common symptom might reduce HRQL and well-being.
