Randomized Trial of Personalized Breast Density and Breast Cancer Risk Notification.
Trial report in Journal of general internal medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02986360 (Informed Implementation of Breast Density Reporting), which is not on this map. Cited by 12 papers, 3 of them syntheses that pooled 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.

Abstract
backgroundDespite widespread implementation of mammographic breast density (MBD) notification laws, the impact of these laws on knowledge of MBD and knowledge of breast cancer risk is limited by the lack of tools to promote informed decision-making in practice.
objectiveTo develop and evaluate whether brief, personalized informational videos following a normal mammogram in addition to a legislatively required letter about MBD result can improve knowledge of MBD and breast cancer risk compared to standard care (i.e., legislatively required letter about MBD included with the mammogram result). DESIGN/
participantsProspective randomized controlled trial of English-speaking women, age 40-74 years, without prior history of breast cancer, receiving a screening mammogram with a normal or benign finding (intervention group n = 235, control group n = 224).
interventionbrief (3-5 min) video, personalized to a woman's MBD result and breast cancer risk. MAIN MEASURES: Primary outcomes were a woman's knowledge of her MBD and risk of breast cancer. Secondary outcomes included whether a woman reported that she discussed the results of her mammogram with her primary care provider (PCP). KEY
resultsRelative to women in the control arm, women in the intervention arm had greater improvement in their knowledge of both their personal MBD (intervention pre/post 39.2%/ 77.5%; control pre/post 36.2%/ 37.5%; odds ratio (OR) 5.34 for change for intervention vs. control, 95% confidence interval (CI) 3.87-7.36; p < 0.001) and risk of breast cancer (intervention pre/post: 66.8%/74.0%; control pre/post 67.9%/ 65.2%; OR 1.42, 95% confidence interval (CI) 1.09-1.84; p = 0.01). Women in the intervention group were more likely than those in the control group to report discussing the results of their mammogram with their PCP (p = 0.05).
conclusionsBrief, personalized videos following mammography can improve knowledge of MBD and personal risk of breast cancer compared to a legislatively mandated informational letter. Trial Registration Clinicaltrials.gov (NCT02986360).
