The effect of information on prostate cancer screening decision process: a discrete choice experiment.
Trial report in BMC health services research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 2 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
backgroundProstate cancer screening is controversial because of uncertainty about its benefits and risks. The aim of this survey was to reveal preferences of men concerning prostate cancer screening and to test the effect of an informative video on these preferences.
methodsA stated preferences questionnaire was sent by e-mail to men aged 50-75 with no history of prostate cancer. Half of them were randomly assigned to view an informative video. A discrete choice model was established to reveal men's preferences for six prostate cancer screening characteristics: mortality by prostate cancer, number of false positive and false negative results, number of overdiagnosis, out-of-pocket costs and recommended frequency.
resultsA population-based sample composed by 1024 men filled in the entire questionnaire. Each attribute gave the expected sign except for overdiagnosis. The video seemed to increase the intention to abstain from prostate cancer screening.
conclusionsThe participants attached greater importance to a decrease in the number of false negatives and a reduction in prostate cancer mortality than to other risks such as the number of false positives and overdiagnosis. Further research is needed to help men make an informed choice regarding screening.
