Gender-based differences in colorectal cancer screening uptake in Singapore: a cross-sectional study.
Article in Family practice, 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
backgroundColorectal cancer screening is an evidence-based preventive approach. Singapore has a national screening programme, but local studies suggest poor uptake. Gender differences in screening uptake exist in the literature, and women in Singapore are exposed to cancer screening (via breast and cervical programmes) earlier than men. This study aimed to identify gender differences, as well as analyse barriers and facilitators associated with being screen-current for colorectal cancer within the genders, using the Health Belief Model.
methodsThis was a cross-sectional study conducted in a large public primary care institution in Singapore. Using consecutive sampling, 426 colorectal cancer screening age-eligible (50 years and above) individuals (232 females, 54.5%) completed a single questionnaire measuring knowledge of colorectal cancer symptoms and prevention, Health Belief Model factors, and colorectal cancer information sources.
resultsWomen had higher knowledge of colorectal cancer symptoms but perceived more barriers. Fewer women were screen-current (33.6%) compared to men (43.4%). Factors associated with knowledge of colorectal cancer symptoms and prevention differed between men (F[13, 178] = 4.51, R2 = 0.138) and women (F[13, 217] = 5.18, R2 = 0.171). Knowledge of symptoms and cues to action was associated with screen-currency in men (Wald χ2 = 33.93, pseudo R2 = 0.18), but the regression model failed to reach significance for women.
conclusionsA one-size-fits-all approach to health promotion is likely insufficient in boosting compliance with colorectal cancer screening recommendations. Further work must be done to understand the more qualitative nuances surrounding women's challenges in being screen-current in Singapore.
