Validation of the 21-Gene Recurrence Score Assay in Patients with Hormone Receptor-Positive, HER2-Negative Breast Cancer and 0 to 3 Positive Lymph Nodes: Risk Pattern and Outcomes on a Community Level.

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: The aim of the present study was to analyze the performance of Oncotype DX® multigene assay (ODX®) in patients with 0-3 lymph nodes in a high-volume community hospital. Methods: Patients with non-metastatic HR*/HER2- EBC and 0-3 positive lymph nodes, who underwent primary surgery at the Red Cross Hospital Munich, Germany and consecutively had ODX® testing were included in this retrospective study. The distribution of clinicopathologic characteristics, recurrence score (RS) risk, and use of systemic therapy were compared among patients without positive lymph nodes (N0) and patients with micrometastases or 1 to 3 positive lymph nodes (N1). Disease-free survival (DFS) and overall survival (OS) were estimated. Results: From 2012 to 2017 ODX® was consecutively performed in 575 (16.4%) of 3,492 women with HR*/HER- EBC, of which 553 were eligible for this analysis (N0: 60.8%; N1: 39.2%). Among the patients included, 441 (79.7%) had an RS of 0 to 25 and 112 (20.3%) had an RS of 26 or higher. In patients with RS 0 to 25 the rate of chemotherapy use was low, independent from nodal status (N0: 17.1% and N1: 19.1%) and 5-year DFS was 90.5% and 91.7% for N0 and N1 patients, respectively. There was no significant difference in DFS (90.5% vs. 93.3%; Conclusions: The results of the study confirm the observations from randomized studies on the use of the ODX® in a real-world population in terms of risk distribution and patient outcome. Adjuvant chemotherapy could be safely omitted in patients with HR*/HER2- breast cancer with 0-3 positive lymph nodes and RS <25.
