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
objectivesComparing the screening performance of different breast cancer screening methods and exploring the applicability of automated breast ultrasonography (ABUS) in rural areas with low health resources in China.
methodsWomen aged 35-64 underwent hand-held ultrasonography (HHUS) and ABUS in Zezhou County, Jincheng City, Shanxi Province, China from 2018 to 2021. Additionally, women aged 45-69 were also screened with mammography (MG). We compared the 3 methods' cancer detection rates, diagnostic accuracy, and overall screening performance, stratified by age groups and breast density. The chi-square test was used to analyze indicators such as sensitivity, specificity, and referral rate.
resultsThe mean age of the 9100 women studied was 45 ± 6.42 years, and 25 cases of breast cancer were identified (2.72‰). The proportion of dense breasts is higher among women aged 45-64 years (67.52%). Compared to the non-dense breast group, the detection rate of breast cancer by MG is significantly reduced in the dense breast group (3.42‰ versus 1.97‰). The diagnostic accuracy rate of ABUS and HHUS for lesions is higher than that of MG (P < .05). The kappa coefficient indicates moderate agreement in diagnostic results between HHUS and ABUS. However, the agreement between HHUS/ABUS and MG is poor. There were no statistical differences in sensitivity and specificity among the 3 screening methods. The referral rate and NNR for ultrasound were lower than those for MG (P < .05), but there were no statistically significant differences between ABUS and HHUS.
conclusionsAmong women with denser breasts, ultrasound has a higher diagnostic accuracy rate compared to MG, and it avoids unnecessary biopsies. Compared to HHUS, ABUS can diagnose malignant tumors more objectively and standardized.
