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

backgroundBody mass index (BMI) has been associated with the risk of esophageal cancer. But the influence of BMI on postoperative complications and prognosis has always been controversial.

methodsBetween 2000 and 2007, 424 patients with esophageal squamous cell carcinoma (ESCC) underwent R0 esophagectomy at our center without neoadjuvant therapy. We performed univariate and multivariate analyses to identify prognostic factors for survival.

resultsPatients were divided into three groups according to Asian-specific BMI cut-off value: underweight (n = 45), normal weight (n = 228), and overweight and obese (n = 151). Mean follow-up time was 39 months. The five-year overall survival (OS) rate was 19%, 34%, and 42% for underweight, normal weight, and overweight and obese, respectively (P < 0.001). The five-year disease-free survival (DFS) rate was 24%, 41%, and 74% for underweight, normal weight, and overweight and obese, respectively (P < 0.001). Multivariate analysis showed that pT, pN, and BMI were independent prognostic factors for DFS and OS. The C-index to the combined model showed improved predictive ability when compared to the pN classification (0.779 vs. 0.734).

conclusionPreoperative BMI was an independent prognostic factor for OS and DFS. The proposed new prognostic model with the pN classification supplemented by BMI might improve the ability to discriminate ESCC patients' outcome.
