1 · What the graph read from 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.

2 · The registry

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

Objective: Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis. Immune checkpoint inhibitor (ICI) monotherapy has shown limited efficacy in PDAC, whereas the potential clinical value of first-line ICI-based combination regimens remains unclear. Through a systematic review and meta-analysis, this study aimed to evaluate the efficacy and safety of first-line ICI-based combination regimens in advanced PDAC. Methods: PubMed, Embase, The Cochrane Library, Scopus, Web of Science, CNKI, Wanfang Data, VIP, and CBM were searched up to April 4, 2026, to identify clinical studies evaluating first-line ICI-based combination therapy for advanced PDAC. Study screening and data extraction were performed in accordance with PRISMA guidelines. Results: Eight clinical trials involving 379 patients were included. In RCT-only analyses, ICI-based combination regimens showed favorable but statistically non-definitive trends for OS (HR = 0.83, 95% CI: 0.65-1.06) and PFS (HR = 0.75, 95% CI: 0.53-1.05), while ORR was improved (OR = 2.19, 95% CI: 1.32-3.64). Single-arm pooled analysis showed a median PFS of 6.2 months and an ORR of 38.0%. In terms of safety, combination therapy increased the risk of specific Grade 3 or higher adverse events, but the overall incidence was clinically manageable. Conclusion: First-line ICI-based combination regimens showed encouraging antitumor activity in advanced PDAC, particularly for radiological response. However, definitive survival benefits were not established in RCT-only analyses, and further large-scale randomized trials are needed.
