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
Introduction: Hereditary predisposition syndromes to cancer represent 5-10% of cancer cases, the most studied being HBOC produced by mutations in the BRCA1/2 genes. Objectives: To describe clinical, histopathological and PV characteristics in patients with HBOC in Córdoba, Argentina and compare it with those without BRCA1/2 mutations. Methods: Cross-sectional, correlational and observational analysis of patients from Córdoba. The ANOVA, Student's t test contingency tables and Fisher exact test were used the significance level was α = 0.05. Results: 155 women with BC, OC and BC/OC were studied. 40 BRCA1 / 2 mutations were identified. No differences were found in the age of diagnosis between patients with and without BRCA1/2 mutations. A significant association was found between VP in BRCA1/2 and the type of cancer (p = 0.003); all cases with BC/OC presented mutations in BRCA1/2. No significant association was found between mutated/non-mutated and personal history, family background, and ER-PR-HER2. 23.1% and 38.1% of BC cases were TN in individuals with VP in BRCA 1 and 2, respectively. The prevalence of mutations was 25.8% and the prevalence of novel PV was 10.0%. Conclusions: Patients with BC-VP BRCA1/2 are associated with ductal histology, and younger age of presentation with VP BRCA1. We did not find significant differences in the age at diagnosis of BC between patients with BRCA1 and BRCA2 mutations, a higher proportion of BC TN is observed than in the general population. In our sample, the prevalence of BRCA1/2 mutations among patients who meet criteria for HBOC is 25.8%, with 10% new pathogenic variant.
