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: As a rare disease, male breast cancer (MBC) is of increasing concern in China. Whether health inequalities of disease burden and healthcare utilization exist by ethnicity in male breast cancer remains unclear. We aim to measure disease burden and healthcare utilization by ethnicity among male breast cancer patients in China. Methods: A retrospective cohort study was established during 2012-2021 based on the Inner Mongolia Regional Health Information Platform. Disease burden, including incidence, 5-year prevalence, mortality, survival rate, and medical cost were analyzed. Results: Among 630 participants (mean [SD] age, 59.4 [13.1] years), age-standardized rates of incidence were 1.2 (95% CI: 0.4-2.1) per 100, 000. All-cause mortality was 50.8 per 1000 person-years (95% CI: 42.4-60.4). Regarding ethnicity, Mongolian had a higher age-standardized 5-year prevalence rate than Han (3.2[95% CI: 2.5-4.0] vs 2.3[95% CI: 1.7-3.0], Conclusions: This study revealed a moderate disease burden and relatively lower healthcare utilization for male breast cancer in Inner Mongolia, China. No significant ethnic disparities existed in disease burden and healthcare utilization. However, increased attention to male breast cancer is warranted due to the crucial influence of economic factors on potential ethnic disparities.
