Breast cancer screening coverage and its association with hospitalisation and mortality: a nationwide ecological study from Poland (2019-2023).
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionBreast cancer is the most frequently diagnosed malignancy among women in Poland and remains a major public health challenge. Population-based screening plays a central role in reducing mortality; however, its effectiveness depends on participation rates and equitable access to healthcare services.
objectiveTo assess breast cancer screening coverage in Poland between 2019 and 2023 and to explore population-level associations between screening coverage, hospitalisations, and mortality.
methodsData were obtained from three national administrative sources: the Ministry of Health's Systemic and Implementation Analyses Database (BASiW), the national mortality registry maintained by Statistics Poland (GUS), and the National Health Fund (NFZ) database (API Statistics NFZ 1.1). Aggregated data from all 16 voivodeships were merged by year and region. Descriptive statistics, Pearson correlation coefficients, and multivariable linear regression models were applied.
resultsThe mean screening coverage during the study period was 50.9%, with substantial regional variation (38.7%-68.2%). A marked decline in screening attendance was observed in 2020, coinciding with the COVID-19 pandemic, followed by gradual recovery in subsequent years. Strong positive correlations were identified between the number of screened women and hospitalisations (r = 0.96) as well as mortality (r = 0.99), largely reflecting population size effects. In multivariable regression analysis (Model 1), higher screening coverage (primary exposure) was statistically associated with lower breast cancer mortality in women aged ≥ 65 years (primary outcome) at the population level (B = - 1.93; p < 0.001). In Model 2, screening coverage was not significantly associated with hospitalisations in women aged 41-60 years (B = -0.81; p = 0.682).
conclusionsBreast cancer screening coverage in Poland remained below the level considered optimal and demonstrated substantial regional disparities. Higher participation was associated with lower mortality at the population level; however, this association should be interpreted descriptively due to the ecological study design. These findings suggest the need for further organisational optimisation and targeted strategies aimed at improving participation in breast cancer screening programmes.
