Immune Checkpoint Inhibitor Combinations in Advanced Ovarian Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Review in Cancers, 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
BACKGROUND/
objectivesImmune checkpoint inhibitors (ICIs) have shown limited efficacy in the treatment of ovarian cancer when used alone. This systematic review and meta-analysis evaluated the impact of different combination partners on ICI efficacy.
methodsPubMed, Embase, CENTRAL, and Web of Science were searched until March 2026 for phase III randomized controlled trials (RCTs) of anti-PD-1/PD-L1 combination regimens. Nine fully published trials (
resultsOverall, ICI combination therapy significantly improved progression-free survival (PFS) (HR 0.83, 95% confidence interval (CI) 0.73-0.93;
conclusionsICI combination therapy improved PFS in advanced ovarian cancer, in contrast to earlier syntheses pooling monotherapy and combination regimens. The benefit was most consistent for bevacizumab-based regimens (GRADE: Moderate); the PARP inhibitor-based benefit was less robust (Low), and chemotherapy combinations offered no advantage (Very low). Subgroup differences were not statistically significant and remain exploratory; a partner-specific, biomarker-guided approach is warranted.
