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

Background: To evaluate the impact of Body Mass Index (BMI) on survival and postoperative complications in older patients with esophageal squamous cell carcinoma (ESCC) following esophagectomy, we designed this study. Materials and methods: We retrospectively analyzed 469 patients aged ≥70 years with thoracic ESCC who underwent esophagectomy at Sichuan Cancer Hospital (May 2016-August 2021). Patients were grouped by WHO BMI categories: underweight (<18.5 kg/m Results: Median follow-up was 47.5 months; R0 resection was achieved in 96.4%. BMI distribution: 7.3% low, 76.8% normal, 16.0% high. Median OS was 44.9 months overall, with no significant OS or DFS differences among BMI groups. RCS demonstrated a significant U-shaped association between continuous BMI and survival: protective ranges were approximately 21.9-27.0 kg/m Conclusion: In elderly ESCC patients after esophagectomy, BMI does not independently influence OS or DFS, though low BMI is associated with specific serious complications. Perioperative optimization-particularly nutritional support for underweight patients-remains essential.
