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

While male breast cancer (MBC) remains a rare and understudied disease, comparatively little is known about its prognosis in contrast to female breast cancer (FBC). There is a paucity of large population-based studies comparing the prognosis of MBC patients to FBC patients in Japan. This study analyzed 181,540 breast cancer cases, 1058 (0.6%) males and 180,482 (99.4%) females, from 12 prefectures in Japan diagnosed between 1993 and 2011. Five- and ten-year net survival (NS) were estimated and stratified by sex, period, age, stage, and histological groups. Excess hazard ratios (EHR) were adjusted for period, age, stage, and histological group. Cochran's Q test was utilized to assess heterogeneity across these factors. The overall 5- and 10-year NS estimates for MBC patients were 90.7% (95% CI: 86.3%-93.7%) and 83.7% (95% CI: 72.2%-90.8%), respectively, while those for FBC patients were 88.3% (95% CI: 88.1%-88.5%) and 79.1% (95% CI: 78.7%-79.4%), respectively. The survival of MBC patients was comparable to that of FBC patients, with EHR of 0.88 [95% CI: 0.70-1.09] and 0.86 [95% CI: 0.69-1.07] for 5- and 10-year survival, respectively. Heterogeneity analysis revealed no significant sex-based differences in survival across these strata. This study offers a comprehensive analysis of breast cancer survival in Japanese men and women and enhances understanding of MBC prognosis relative to FBC.
