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

purposeTo evaluate whether regional treatment settings are associated with differences in the clinical outcomes among older gastric cancer patients undergoing curative gastrectomy.

methodsThis multicenter retrospective study included 327 patients aged ≥ 80 years who underwent curative gastrectomy for gastric cancer. The patients were classified into urban (n = 118) and rural (n = 209) groups. The baseline characteristics, surgical outcomes, and long-term outcomes were compared.

resultsPatients in rural areas had poorer performance statuses, more comorbidities, worse nutritional and inflammatory profiles, and longer distances to the hospital. However, no differences were observed between the urban and rural groups in terms of the surgical approach, postoperative complication rates, or the administration of adjuvant chemotherapy. The 5-year overall survival rates in the rural and urban groups were 66.6% and 59.8%, respectively (p = 0.197). A multivariate Cox regression analysis identified Eastern Cooperative Oncology Group performance status ≥ 2 (hazard ratio: 2.02), carcinoembryonic antigen ≥ 5 ng/mL (hazard ratio: 1.92), pathological stage III (hazard ratio: 3.72), and Clavien-Dindo grade ≥ III complications (hazard ratio: 2.51) as independent predictors of overall survival.

conclusionThe comparable surgical and long-term survival outcomes between patients treated in rural and urban areas suggest that equitable surgical care may be achievable across different geographic settings.
