Efficacy and Safety of Ribociclib Plus Endocrine Therapy Versus Endocrine Therapy Alone in HR-Positive/HER2-Negative Breast Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Article in Clinical Medicine Insights. Oncology, 2025. 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: Recent trials of ribociclib, a cyclin-dependent kinase inhibitor, have shown promising results in patients with hormone receptor-positive (HR+)/HER2-negative (HER2-) breast cancer. This meta-analysis evaluates the efficacy and safety of combining ribociclib with endocrine therapy (ET) versus ET alone in this patient population. Methodology: A comprehensive search of PubMed, Embase, CENTRAL, Scopus, and Web of Science (up to July 2024, no language restrictions) identified randomized controlled trials (RCTs) comparing endocrine therapy (ET) with and without ribociclib for HR+/HER2- breast cancer. Bias was assessed using Cochrane's Risk of Bias tool. Hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS) and odds ratios (ORs) for Grade III + adverse effects (neutropenia, hepatobiliary toxicity, QT prolongation, and interstitial pneumonitis) were calculated with 95% confidence intervals (CI). A random-effects model accounted for heterogeneity ( Results: The meta-analysis of 5 RCTs (7286 participants) showed ribociclib plus ET significantly improved OS (HR 0.76, 95% CI 0.68-0.85, Conclusion: Ribociclib combined with ET improves OS and PFS but is associated with higher rates of adverse effects, compared with ET alone, highlighting the need for careful monitoring and management. Funding: None.
