Possible muscle-sparing advantage and bodyweight maintenance of laparoscopic gastrectomy for older patients with locally advanced gastric cancer.

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
purposeLaparoscopic gastrectomy (LG) is a promising approach for older patients who require less invasive surgery because of their reduced functional reserve and increased comorbidities, with the expansion of its indication to locally advanced gastric cancer. However, the specific benefits of LG in older patients remain unclear. We evaluated whether LG positively influences the postoperative maintenance of skeletal muscle (SM) and bodyweight (BW).
methodsWe retrospectively analyzed the data of consecutive patients aged ≥ 75 years who underwent open gastrectomy (OG) and LG for cStage II or III gastric cancer between 2016 and 2021. After adjustment using propensity score matching, surgical and postoperative outcomes were compared between the groups including the postoperative changes of SM index (%SMI) and BW (%BW).
resultsA total of 167 patients who underwent OG (n = 93) and LG (n = 74) were included in the study. After matching, 48 patients in each group were eligible. No significant difference in postoperative complications was observed. Both %SMI and %BW after LG were significantly maintained compared with those after OG during the postoperative first year. LG had consistently positive effects on the maintenance of %SMI and %BW across the prespecified subgroups. Notably, patients with body mass index < 25, performance status 0-1, non-total gastrectomy, and absence of adjuvant chemotherapy benefited from LG in the maintenance of %SMI and %BW.
conclusionLG offers greater advantages over OG in maintaining postoperative SM mass as well as BW in patients aged ≥ 75 with locally advanced gastric cancer.
