1 · What the graph read from it

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.

2 · The registry

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: Male breast cancer (MBC) is a rare disease. Limited studies have investigated Chinese MBC patients or compared them with patients in other countries. This study aims to explore the features of Chinese MBC patients by comparing them with their American counterparts. Methods: We retrospectively collected data of Chinese MBC patients from 36 centers in China and American MBC patients from the Surveillance, Epidemiology, and End Results database, all of which were diagnosed between 1988 and 2020. Overall survival (OS) comparisons were evaluated by the Kaplan-Meier method, log-rank test, and Cox regression analyses. Results: In total, 1,119 Chinese MBC patients and 11,522 American patients were included. Comparatively, Chinese patients were younger (mean ± standard deviation: 60.9±12.7 in China Conclusions: The disparities in characteristics and treatment between Chinese and American MBC patients were demonstrated. Chinese patients tended to receive more aggressive surgery as well as chemotherapy and present with different OS even after adjustments.
