Reduced Mammography Screening for Breast Cancer among Women with Visual Impairment.
Article in Ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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.
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
purposeTimely mammography to screen for breast cancer in accordance with the United States Preventive Services Task Force (USPSTF) recommendations can reduce morbidity and mortality substantially. This study assessed whether the odds of undergoing screening mammography are similar for women with and without visual impairment (VI).
designRetrospective, longitudinal cohort study.
participantsWomen aged 65 to 72 years enrolled in fee-for-service Medicare from January 1, 2008, through December 31, 2015.
methodsPatients with no vision loss (NVL), partial vision loss (PVL), and severe vision loss (SVL) were matched 1:1:1 based on age, race, time in Medicare, urbanicity of residence, and overall health. Women with pre-existing breast cancer were excluded. Multivariable conditional logistic regression modeling compared the odds of undergoing screening mammography within a 2-year follow-up period among the 3 groups. MAIN OUTCOMES MEASURES: Proportion of participants undergoing mammography and adjusted odds ratios (ORs) of undergoing mammography within 2 years of follow-up.
resultsA total of 1044 patients were matched (348 in each group). The mean ± standard deviation age at the index date was 69.0 ± 1.5 years for all 3 groups. The proportion of women undergoing 1 mammography screening or more within the 2-year follow-up was 69.0% (n = 240), 56.9% (n = 198), and 56.0% (n = 195) for the NVL, PVL, and SVL groups, respectively (P = 0.0005). The mean ± standard deviation number of mammography screenings undergone per patient during the 5-year period (3-year look-back plus 2-year follow-up) was 3.1 ± 2.0, 2.5 ± 2.0, and 2.3 ± 2.1 for the NVL, PVL, and SVL groups, respectively (P < 0.0001). Women with SVL had 42% decreased odds (OR, 0.58; 95% CI, 0.37-0.90; P = 0.01), and those with PVL had 44% decreased odds (OR, 0.56; CI, 0.36-0.87; P = 0.009) of undergoing mammography during follow-up compared with those with NVL.
conclusionsWomen with VI were significantly less likely to undergo mammography screening for breast cancer than women without VI. Clinicians should look for ways to help ensure that patients with VI undergo mammography and other preventive screenings as recommended by the USPSTF.
