Significance of Preoperative Pulmonary Function on Short- and Long-Term Outcomes Following Gastrectomy for Gastric Cancer.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundPreoperative pulmonary function assessment is useful for selecting surgical candidates and operative methods and assessing the risk of postoperative pulmonary complications. However, few studies have investigated the relationship between preoperative pulmonary function and short- and long-term outcomes in patients who underwent gastrectomy for gastric cancer.
methodsOf the 1040 patients with gastric cancer (stages I-III) who had undergone R0 gastrectomy between 2009 and 2020, 750 who underwent preoperative spirometry were included. Restrictive ventilatory impairment was defined as a vital capacity of the predicted value (%VC) < 80%, while obstructive ventilatory impairment was defined as forced expiratory volume in one second (FEV1%) < 70%. Postoperative complications were assessed using the Clavien-Dindo (CD) classification. The relationship between clinical factors, including %VC, FEV1%, severe postoperative complications (CD ≥ 3b), overall survival (OS), and relapse-free survival, were assessed.
resultsThe mean age of the 750 patients was 68 ± 10.5 years. Severe postoperative complications were observed in 25 (3.3%) patients and were significantly associated with FEV1% < 70% in the univariate analysis. The 5-year OS was 72.5%. Multivariate analysis showed that the cancer stage, age > 75 years, preoperative comorbidities, %VC < 80%, total gastrectomy, severe postoperative complications, and postoperative adjuvant chemotherapy were the significant independent factors affecting OS. Pneumonia was significantly associated with %VC < 80%.
conclusionsFEV1% < 70%was associated with the development of severe postoperative complications, while %VC < 80% was associated with poor OS independent of the cancer stage because of death from pneumonia. Spirometry helps surgeons and patients discuss the risks and benefits of surgery.
