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

backgroundDespite the availability of colorectal cancer (CRC) screening, participation rates in Japan remain low. Although knowledge about CRC has been identified as a predictor of screening uptake, data specific to the Japanese population remain limited. We aimed to examine the associations between knowledge of CRC risk factors and knowledge of cancer screening, with CRC screening attendance in Japan.

methodsA nationwide cross-sectional survey was conducted among 1,966 Japanese adults aged 40-69 years. Associations between correct answers on CRC risk factors and cancer screening, and CRC screening attendance were analyzed using multiple logistic regression, adjusting for relevant covariates.

resultsSeventy percent of participants had undergone CRC screening. A significant positive linear association was observed between knowledge of CRC risk factors and CRC screening attendance (P for trend < 0.01). Similarly, greater knowledge of cancer screening was significantly associated with higher attendance (P for trend < 0.01).

conclusionAccurate knowledge of CRC risk factors and cancer screening was positively associated with CRC screening attendance. These findings show the importance of disseminating accurate information to the Japanese population; however, further prospective studies are needed to examine this association more thoroughly.
