Strategies for increasing mammography screening in primary care in Chile: results of a randomized clinical trial.
Trial report in Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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.
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
backgroundBreast cancer is the cancer with the highest incidence among women in Chile and in many Latin American countries. Breast cancer screening has very low compliance among Chilean women.
methodsWe compared the effects on mammography screening rates of standard care, of a low-intensity intervention based on mail contact, and of a high-intensity intervention based on mail plus telephone or personal contact. A random sample of 500 women with the age of 50 to 70 years registered at a community clinic in Santiago who had not had a mammogram in the past 2 years were randomly assigned to one of the three intervention groups. Six months after randomization, participants were re-evaluated for their compliance with mammography screening. The outcome was measured by self-report and by electronic clinical records. An intention to treat model was used to analyze the results.
resultsBetween 92% and 93% of participants completed the study. Based on electronic records, mammography screening rates increased significantly from 6% in the control group to 51.8% in the low-intensity group and 70.1% in the high-intensity group. About 14% of participants in each group received opportunistic advice, 100% of participants in the low- and high-intensity groups received the mail contact, and 50% in the high-intensity group received a telephone or personal contact.
conclusionA primary care intervention based on mail or brief personal contact could significantly improve mammogram screening rates. IMPACT: A relatively simple intervention could have a strong impact in breast cancer prevention in underserved communities.
