Body mass index affects postoperative daily activities of older patients after gastrectomy.
Observational study in European geriatric medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
purposeThis study aimed to examine the impact of preoperative body mass index (BMI) on postoperative activities of daily living (ADL) and clinical outcomes in older patients who underwent curative gastrectomy.
methodsThis was a retrospective observational study using a nationwide inpatient database in Japan. The study included 1769 patients with gastric cancer, aged ≥ 65 years old, who underwent gastrectomy. BMI was defined as per the World Health Organization classifications for Asian populations. Primary outcome was ADL at discharge, assessed by Barthel index. Secondary outcomes included postoperative complications and length of hospital stay.
resultsPatients analyzed included 890 (50.3%) aged 65-74 years, 745 (42.1%) aged 75-84 years, and 134 (7.6%) aged ≥ 85 years; 71.5% were male. According to BMI classification, 11.9% patients were considered underweight (< 18.5 kg/m
conclusionPerioperative management with a focus on BMI is important in older patients undergoing elective curative gastrectomy.
