Comparison of Weight and Body Composition After Gastrectomy Between Elderly and Non-elderly Patients With Gastric Cancer.
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
backgroundBody weight, especially lean body mass, significantly decreases after gastrectomy for gastric cancer due to surgical invasion, reduced food intake, and reduced mobility, which can reduce the quality of life and induce associated toxicity or reduce compliance with adjuvant chemotherapy. Such risks can be particularly high in elderly patients with gastric cancer. However, whether or not changes in the weight and body composition differ between elderly and non-elderly patients remains unclear. PATIENTS AND
methodsThis retrospective study examined patients who underwent curative surgery for gastric cancer between May 2010 and February 2017. Body weight and composition were evaluated by a bioelectrical impedance analyzer within 1 week before surgery, at 1 week after surgery, and at 1 and at 3 months after surgery. Patients were classified as elderly (≥80 years) or non-elderly (<80 years).
resultsEight-hundred and eighty-eight patients (84 elderly and 804 non-elderly) were entered into the present study. Patient background, surgical and clinicopathological factors, and surgical complications did not significantly differ between the two groups. Body weight loss at 1 week, and at 1 and 3 months after surgery, defined as the decrease from the preoperative value, were -2.8%, -6.5%, and -9.0%, respectively, in the elderly and -3.5%, -6.0%, and -8.1%, respectively, in the non-elderly patients (p=0.111, 0.125, and 0.153, respectively). The corresponding losses of lean body mass were -2.6%, -6.0%, and -6.4%, respectively, in the elderly and -3.5%, -4.9%, and -4.7%, respectively, in the non-elderly patients, with p-values of 0.056, 0.036, and 0.029, respectively.
conclusionDecreases in lean body mass after gastrectomy were greater in elderly than in non-elderly patients. In order to maintain lean body mass among elderly patients, additional care and treatments are needed.
