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

purposeThere is an increasing incidence of young breast cancer (YBC) patients with uncertainty surrounding the factors and patterns that are contributing.

methodsWe obtained characteristics and survival data from 206,156 YBC patients (≤ 40 years of age) diagnosed between 2005 and 2019 from the National Cancer Database (NCDB). Patients were subdivided into two comparison groups based on year of diagnosis (2005-2009, Old vs. 2015-2019, New group). A Chi-square test of independence was employed to measure the changes. Cox proportional hazards model was used to explore the variables influencing overall survival (OS).

resultsComparison between Old (55,397 patients) and New groups (67,930 patients) showed an increase in the proportion of Hispanic (8.4% vs 10.0%), Black (16.0% vs 16.6%), and Asian (4.8% vs 6.7%) populations. In the New group, black patients had a significantly worse OS, p < 0.001. Additionally, there was a reduction in the proportion of patients with private insurance (43,940 (81.7%) vs 51,104 (76.4%)) and an increase in patients with Medicaid (5,893 (11.0%) vs 10,694 (16.0%)). Finally, there was a significant increase in hormone positive disease (35,142 (70.0%) vs 49,409 (75.8%), p = < 0.001).

conclusionsWithin YBC patients, the proportion of underrepresented and underserved population is increasing, with an impact on OS. We also see an increase in hormone positive disease. Awareness of these at-risk populations is important for early identification of breast cancer and mitigation of poorer outcomes. Also, there are increasing rates of hormone positive disease which can cause substantial personal and societal implications, such as impacts on family planning and early menopause.
