Validating Khorana Risk Score in gastric cancer patients on immune checkpoint inhibitors and chemotherapy.
Article in Immunotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionPatients with gastric cancer are at a high risk of venous thromboembolism (VTE), and immune checkpoint inhibitors (ICIs) may further increase this risk. While the Khorana Risk Score (KRS) has been validated primarily in chemotherapy-treated populations, its utility in ICI-treated patients remains unclear.
methodsUsing the TriNetX Global Collaborative Network, we analyzed data from 2782 patients with gastric cancer treated with ICIs. Patients were stratified into high-risk (KRS ≥3) and intermediate-risk (KRS = 2) groups based on pre-treatment laboratory values and BMI. Cox proportional-hazards analyses were performed to evaluate the association between KRS and outcomes, including VTE, all-cause mortality, and arterial thrombosis, over a one-year follow-up period.
resultsHigh-risk patients had a 26% higher risk of VTE (HR: 1.26, [95% CI: 1.06-1.50]) and a 43% higher risk of all-cause mortality (HR: 1.43, [95% CI: 1.27-1.62]) compared to intermediate-risk patients. The incidence of deep vein thrombosis (DVT) was also significantly higher in the high-risk group (HR: 1.27, [95% CI: 1.01-1.59]), but no significant differences were observed for pulmonary embolism (PE) or arterial thrombosis.
conclusionThese findings suggest the KRS may effectively stratify VTE risk and mortality in gastric cancer patients treated with ICIs.
