The relationship between post-diagnostic statin usage and breast cancer prognosis varies by hormone receptor phenotype: a systemic review and meta-analysis.

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
backgroundPreclinical studies and epidemiologic data had indicated statins had antineoplastic properties in breast cancer patients. Since breast cancer treatment is based on its phenotype, it is important to explore influence of post-diagnosis statin usage on breast cancer patients with different phenotypes.
methodsWe searched the related studies between inception and August, 2019 from MEDLINE and EMBASE. A total of 7 studies with 24,541 patients were identified. Stata/SE 15.0 and Review Manager 5.3 were used to analyze data. Inconsistency index was used to estimate heterogeneity. Begg's and Egger's regression test was used to examine publication bias.
resultsOverall post-diagnostic statin use was associated with improved recurrence free survival (recurrence free survival (RFS); hazard ratio (HR) 0.74; 95% confidential interval (95% CI) 0.57-0.98), overall survival (overall survival (OS); HR 0.53; 95% CI 0.31-0.91) and cancer-specific survival (cancer-specific survival (CSS); and HR 0.61; 95% CI 0.41-0.91). In hormone receptor positive patients, statin use was associated with improved CSS (HR 0.74, 95% CI 0.65-0.84). No protective effect was found in either OS or RFS. In hormone receptor negative patients, statin was associated with reduced OS (HR 2.19, 95% CI 1.34-3.59) and reduced RFS, but without statistical significance.
conclusionsPost-diagnostic statin use was associated with improved RFS, OS and CSS in breast cancer patients. Subgroup analysis indicted that the benefits of statin usage varied from hormone receptor phenotype type. Prospective randomized trial with patients of different hormone receptor types might be needed to help identify which subtype of breast cancer patients would benefit from post-diagnostic statin usage.
