Sensitivity and specificity of screening mammography without clinical breast examination among Japanese women aged 40-49 years: analysis of data from the J-START results.
Article in Breast cancer (Tokyo, Japan), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
backgroundCurrent breast cancer screening programs worldwide offer only mammography for asymptomatic women, without clinical breast examination (CBE). The sensitivity and specificity of true asymptomatic screening mammography are important, especially in Japan.
methodsThis study used data from the Japan Strategic Anti-cancer Randomized Trial (J-START) results, and then calculated the sensitivity and specificity of screening mammography without CBE among Japanese women aged 40-49 years.
resultsThe sensitivity and specificity of modern film mammography, performed biennially, among Japanese women aged 40-49 years were 71.7% and 92.6%, respectively. The sensitivity of mammography alone was 47.4%. From the secondary analysis, the sensitivity of mammography alone was 44.1% for women with dense breasts and 34.8% for women with non-dense breasts.
conclusionThe sensitivity of mammography alone of 47.4% is too low. The low sensitivity of screening mammography for true asymptomatic Japanese women aged 40-49 years places this population at an elevated risk, which can justify performing adjunctive ultrasonography.
