Optimal First-line Immune-related Therapy Selection for Advanced Gastric Cancer: A Systematic Review and Network Meta-analysis.
Synthesis in Journal of gastrointestinal cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeAlthough immune checkpoint inhibitors combined with chemotherapy improve survival in advanced gastric cancer (AGC), comparative evidence across first-line regimens remains insufficient. This study aimed to systematically evaluate their relative efficacy and safety.
methodsPubMed, Embase, the Cochrane Library, Web of Science, and major conferences were searched up to February 28, 2025. Eligible RCTs comparing ICI-related regimens as first-line AGC treatment were included. Primary outcomes were overall survival (OS) and progression-free survival (PFS).
resultsEleven RCTs involving 8,999 patients, six integrated strategies, and twelve specific regimens were included. Dual-target ICI-chemo and single ICI-chemo showed significant survival benefits over chemotherapy, whereas dual ICIs±chemo and single ICI alone did not. Dual-target ICI-chemo was associated with significantly better survival than both dual ICIs±chemo and single ICI±chemo. Among the specific regimens, cadon-chemo achieved the most favorable OS and PFS. No significant OS differences were observed among the single ICI-chemo regimens. In PD-L1-positive subgroups, both dual-target ICI-chemo and single ICI-chemo significantly improved survival compared with chemotherapy, with cadon-chemo being most effective in CPS ≥ 10 and CPS ≥ 1, and SHR1701-chemo in CPS ≥ 5. In the CPS < 5 subgroup, dual-target ICI-chemo significantly improved OS, while single ICI-chemo showed a trend toward benefit. However, no ICI-based strategy demonstrated benefit in CPS < 1.
conclusionsDual-target ICI-chemo appears to be the most effective first-line strategy for AGC based on current indirect evidence, surpassing single ICI-chemo and dual ICI-based regimens. These findings support personalized therapy selection but await confirmation by head‑to‑head trials. Future studies should address CPS < 1 and explore optimized combinations to enhance outcomes.
