The 10-year Landscape of United States-Registered Parkinson Disease Clinical Trials: 2007-2016.
Article in Movement disorders clinical practice. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWe know little about how well the goals and results of clinical trials in Parkinson disease (PD) reflect the priorities of patients and the broader PD community.
objectivesWe conducted a review of registered trials on http://clincialtrials.gov from 2007 to 2016 to explore whether PD trials have moved closer to the therapeutic priority goals articulated by the PD community.
methodsUsing the search terms: Parkinson, interventional trials, phase "0-4," we categorized therapeutic PD studies from http://clinicaltrials.gov between January 1, 2007 and December 31, 2016. Seven hundred and sixty-six trials met the criteria for analysis. We explored temporal trends in the utilization of balance problems and falls; mood symptoms, including stress and anxiety; cognitive dysfunction, including dementia; and dyskinesias as primary outcomes. We analyzed trials where recruitment was listed as "completed" (n = 391) to explore publication rates.
resultsBalance problems and falls were listed as primary outcome measures in 125 studies (16.3%), cognitive measures in 48 (6.3%), mood features in 37 (4.8%), and dyskinesias in 30 (3.9%). Trials using balance problems and falls as a primary outcome increased in frequency per year between 2007 and 2016 (Z = -2.128,
conclusionsPD trials focusing on balance problems and falls are becoming more common. About 40% of completed PD trials are unpublished, reflecting suboptimal utilization of participant efforts.
