Short-term outcomes of preoperative computed tomography angiography versus standard assessment in patients with BMI ≥ 25.0 kg/m
Trial report in Gastric cancer : official journal of the International Gastric Cancer Association and the Japanese Gastric Cancer Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04636099 (Preoperative CTA to Evaluate the Influence of Gastric Artery Type on the Clinical Outcome of Gastric Cancer Patients With BMI≥25.0 kg/m2：A Multicenter Randomized Controlled Study), which is not on this map.

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.

Abstract
backgroundLaparoscopic gastrectomy lacks hand-direct tactile sense and has a limited surgical field compared to laparotomy. Apart from textbook classification, there are anatomical variations in the gastric arteries. Laparoscopic gastrectomy presents technical difficulties and necessitates a more comprehensive comprehension of regional anatomy than open surgical procedures. We aimed to compare efficacy and safety of preoperative computed tomography angiography (CTA) associated with surgical decision-making for laparoscopic gastrectomy.
methodsThe GISSG 20-01 study was a multicenter, open-label, randomized clinical trial. The enrollment criteria mainly included histologically confirmed gastric cancer patients with BMI ≥ 25 kg/m
resultsBetween November 2020 and December 2021, 382 patients were enrolled and randomly assigned. After exclusion of 25 patients, 357 patients were included in the modified intention-to-treat population (179 in the CTA group and 178 in the non-CTA group). The mean intraoperative blood loss (CTA vs non-CTA; 74.2 vs 95.0 mL, P = 0.005) and operation time (215.4 vs 231.2 min, P = 0.004) was significantly lower in the CTA group. Total number of retrieved lymph nodes was similar in two groups (32.2 vs 30.2, P = 0.070). The CTA group had a significantly lower surgery task load index sore than the non-CTA group (36.6 vs 41.7, P < 0.001). There was no significant difference in postoperative complications rate of 14.5% in the CTA group and 22.5% in the non-CTA group (difference, - 8.0% [95% CI, - 16.0 to 0.1]; P = 0.053).
conclusionPreoperative CTA associated with surgical decision-making could relieve surgery burden and lead to a better surgical performance compared with non-CTA support, which including decreased blood loss volume, vessel damage and operation time.
