Five-year follow-up study of a population-based prospective cohort of men with low-risk prostate cancer: the treatment options in prostate cancer study (TOPCS): study protocol.

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
introductionActive surveillance (AS) is recommended for men with low-risk prostate cancer (LRPC) to reduce overtreatment and to maintain patients' quality of life (QOL). However, whether African American (AA) men can safely undergo AS is controversial due to concerns of more aggressive disease and lack of empirical data on the safety and effectiveness of AS in this population. Withholding of AS may lead to a lost opportunity for improving survivorship in AA men. In this study, peer-reviewed and funded by the US Department of Defense, we will assess whether AS is an equally effective and safe management option for AA as it is for White men with LRPC. METHODS AND ANALYSIS: The project extends follow-up of a large contemporary population-based cohort of LRPC patients (n=1688) with a high proportion of AA men (~20%) and well-characterised baseline and 2-year follow-up data. The objectives are to (1) determine any racial differences in AS adherence, switch rate from AS to curative treatment and time to treatment over 5 years after diagnosis, (2) compare QOL among AS group and curative treatment group over time, overall and by race and (3) evaluate whether reasons for switching from AS to curative treatment differ by race. Validation of survey responses related to AS follow-up procedures is being conducted through medical record review. We expect to obtain 5-year survey from ~900 (~20% AA) men by the end of this study to have sufficient power. Descriptive and inferential statistical techniques will be used to examine racial differences in AS adherence, effectiveness and QOL. ETHICS AND DISSEMINATION: The parent and current studies were approved by the Institutional Review Boards at Wayne State University and Emory University. Since it is an observational study, ethical or safety risks are low. We will disseminate our findings to relevant conferences and peer-reviewed journals.
