Does Hepatic Metastasectomy for Breast Cancer Oligo-Metastasis to the Liver Offer Survival Advantage? Systematic Review and Meta-Analysis.
Review in Journal of the West African College of Surgeons. 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: The impact of liver resection on survival in patients with hepatic metastasis from breast cancer has remained a controversial topic, with multiple studies reporting conflicting results. Objective: We perform this meta-analysis comparing metastasectomy to systemic therapy in terms of survival outcomes in cases of hepatic oligo-metastasis from breast cancer. Materials and Methods: A systematic search of PubMed, Embase, and Cochrane Library was conducted for relevant studies. The search terms used included "Breast Neoplasms," "Liver," hepatic" "Metastasis" "Hepatectomy," "Metastasectomy" "resection," and "surgery." The primary outcome was overall survival (OS). Only studies published in English and studies that compared OS between patients that had metastasectomy and those that received systemic therapy were included. Results: Thirteen studies were included in the meta-analysis. The one year overall survival of patients who had surgery is superior to those who received systemic therapy only, with a risk ratio (RR) of 7.59 and Conclusion: Hepatic metastasectomy in combination with systemic therapy is superior to systemic therapy alone in patients with breast cancer and oligo-metastasis of the liver.
