Perioperative outcomes and long-term survival following resection of gallbladder cancer in older adults: retrospective study.
Article in BJS open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundGallbladder cancer (GBC) is a rare but aggressive disease, and surgical resection remains the only potential curative treatment. Although tumour-related effects on prognosis are well established, the impact of age is less understood. This study aimed to evaluate the influence of age on overall survival (OS), recurrence-free survival (RFS), and perioperative complications in GBC.
methodsData from patients undergoing curative resection for GBC at 133 centres across 41 countries between 2010 and 2020 were analysed to determine the prognostic association of age ≥ 75 years with OS, RFS, and morbidity. Propensity score matching was used to address confounders between the two age groups.
resultsIn all, 4138 patients underwent surgery for GBC. Patients with macroscopic tumour remaining after surgery, metastatic disease, only high-grade dysplasia were excluded leaving 3676 patients for analyses. Full data on all relevant parameters was available for 2072 patients aged < 75 years and 633 patients aged ≥ 75 years. Patients aged ≥ 75 years had more co-morbidities, underwent less extensive surgery or lymphadenectomy, and received adjuvant chemotherapy less frequently than younger (< 75 years) patients. Age ≥ 75 years was associated with poorer OS in both the unmatched (hazard ratio (HR) 1.34; 95% confidence interval (c.i.) 1.14 to 1.56; P < 0.001) and matched cohorts (HR 1.31; 95% c.i. 1.12 to 1.54; P < 0.001) cohorts, but was not associated with RFS or 1-year survival. Tumour extent and nodal stage had the greatest association with OS and RFS. Age was not associated with increased complications in either the unmatched (odds ratio (OR) 1.11; 95% c.i. 0.85 to 1.45; P = 0.400) or matched (OR 0.90; 95% c.i. 0.72 to 1.12; P = 0.353) cohorts.
conclusionsOlder adults received less extensive surgery and infrequent adjuvant chemotherapy. Age ≥ 75 years was associated with poorer OS following GBC resection but comparable complication rates to younger adults. Older adults of sufficient fitness should not be denied curative treatment based on age, and oncological benefit should be balanced against perioperative risk to personalize treatment and optimize surgical outcomes.
