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

backgroundIncidences of esophageal cancer and obesity are both rising in the United States. The aim of this study was to determine the influence of elevated body mass index on outcomes after esophagectomy for cancer.

methodsOverall and disease-free survivals in obese (BMI ≥ 30), overweight (BMI 25-29), and normal-weight (BMI 20-24) patients undergoing esophagectomy constituted the study end points. Survivals were calculated by the Kaplan-Meier method, and differences were analyzed by log rank method.

resultsThe study included 166 obese, 176 overweight, and 148 normal-weight patients. These three groups were similar in terms of demographics and comorbidities, with the exception of younger age (62.5 vs. 66.2 vs. 65.3 years, P = 0.002), and higher incidence of diabetes (23.5 vs. 11.4 vs. 10.1%, P = 0.001) and hiatal hernia (28.3 vs. 14.8 vs. 20.3%, P = 0.01) in obese patients. Rates of adenocarcinoma histology were higher in obese patients (90.8 vs. 90.9 vs. 82.5%, P = 0.03). Despite similar preoperative stage, obese patients were less likely to receive neoadjuvant treatment (47.6 vs. 54.5 vs. 66.2%, P = 0.004). Response to neoadjuvant treatment, type of surgery performed, extent of lymphadenectomy, rate of R0 resections, perioperative complications, and administration of adjuvant chemotherapy were not influenced by BMI. At a median follow-up of 25 months, 5-year overall and disease-free survivals were longer in obese patients (respectively, 48, 41, 34%, P = 0.01 and 48, 44, 34%, P = 0.01).

conclusionsIn our experience, an elevated BMI did not reduce overall and disease-free survivals after esophagectomy for cancer.
