Breast and cervical cancer screening in a semi-urban African setting: evidence from Franceville, Gabon (2015-2021).
Article in Frontiers in oncology, 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
Background: Breast and cervical cancers are among the most frequent malignancies in women worldwide and represent a growing public health concern in sub-Saharan Africa (SSA). In Gabon, national screening programs have been established, but their effectiveness remains poorly documented, particularly outside the capital city, Libreville. This study, therefore, aimed to describe the screening outcomes and associated factors for breast abnormalities and suspected cervical lesions at the Centre Hospitalier Universitaire Amissa Bongo (CHUAB) in Franceville, Gabon. Methods: We conducted a retrospective cross-sectional study that included all women who attended routine screening at CHUAB between 2015 and, 2016 and, 2018 and 2021. Data were retrieved from hospital registries and medical records. All women underwent both clinical breast examination (CBE) and visual inspection with acetic acid (VIA). Sociodemographic, reproductive, and clinical variables were analyzed to determine their associations with screening outcomes using univariable and exploratory multivariable logistic regression models. Results: A total of 1,328 women were included in the study, with a mean age of 35.4 ± 10.8 years. In univariable analysis, women aged 45-73 years had lower odds of cervical screening positivity compared with those aged 14-25 years (OR = 0.52, 95% CI: 0.29-0.90; p = 0.021). In exploratory multivariable analysis, non-Gabonese nationality and employment in the public sector were associated with cervical screening positivity. Regarding breast abnormalities, an age at first pregnancy between 30 and 39 years was associated with higher odds of screening positivity in univariable analysis (OR = 3.90, 95% CI: 1.07-11.4; p = 0.021); however, no factors remained statistically significant in the adjusted model. Conclusion: This study offers one of the first accounts of routine breast and cervical cancer screening outcomes in a semi-urban setting in south-eastern Gabon. VIA and CBE detected a measurable proportion of women with suspected cervical lesions and breast abnormalities, underscoring the value of these simple and accessible screening approaches in resource-limited settings. Strengthening follow-up systems, improving data management, and expanding screening coverage could further enhance cancer control among women in Gabon.
