Hyperthermic intraperitoneal chemotherapy plus SOX chemotherapy versus SOX chemotherapy alone in patients with gastric cancer and peritoneal metastasis: a phase II randomized clinical trial.
Article in Journal of gastrointestinal oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03604614 (A Randomized Controlled Clinical Trial of Hyperthermic Intraperitoneal Chemotherapy for Advanced Gastric Cancer With Peritoneal Metastatis), 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.

Abstract
Background: The prognosis of patients with gastric cancer with peritoneal metastasis (GCPM) is exceedingly poor. This study evaluated the efficacy and safety of hyperthermic intraperitoneal chemotherapy (HIPEC) with paclitaxel combined with S-1 and oxaliplatin (SOX) in the treatment of GCPM. Methods: Patients with pathologically confirmed primary gastric adenocarcinoma and laparoscopy-confirmed peritoneal metastasis were enrolled and randomized to receive either HIPEC plus SOX (HIPEC group) or SOX alone (SOX group). The primary endpoint was progression-free survival (PFS), and the secondary endpoints were 1-year survival rate, overall survival (OS), and safety. Results: Among the included patients, 30 were assigned to the HIPEC group and 29 to the SOX group. Compared to the HIPEC group, the SOX group had a significantly higher median PFS (SOX: median 8.5 months, IQR, 3.8-21.8 months; HIPEC: median 6.1 months, IQR, 3.3-10.8 months; P=0.004) and OS (SOX: median 13.0 months, IQR, 6.3-16.6 months; HIPEC: median 10.0 months, IQR, 5.2-24.0 months; P=0.02). The 1-year survival rate was 50.0% in the SOX group and 37.9% in HIPEC group, but the difference was not statistically significant. No serious adverse events related to the protocol treatment occurred in any patients. Conclusions: This trial failed to show the superiority of HIPEC with SOX over SOX alone. Further research into this regimen is needed. Trial Registration: ClinicalTrials.gov NCT03604614.
