15-White Dots APP-Coo-Test: a reliable touch-screen application for assessing upper limb movement impairment in patients with cerebellar ataxias.
Article in Journal of neurology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
backgroundThe use of objective measurements is essential to assess disease progression and to evaluate the effectiveness of rehabilitation protocols and clinical treatments.
aimThe purpose of this study was to develop a touch-screen application, that we named 15-White Dots APP-Coo-Test (15-WDACT), able to carry out quantitative and objective measurements of the rapid and coordinated upper limb movements, typically impaired in patients with cerebellar ataxias (CA).
methodsA total of 87 CA patients and 170 healthy subjects participated in this study. The subject was asked to touch with their index finger a white dot, appearing consecutively and randomly on the screen at different positions, for a total of 15 dots per session. The score is the execution time of a single session.
results15-WDACT measurements have highly correlated with the scores obtained with the Scale for the Assessment and Rating of Ataxia (SARA), with the Composite Cerebellar Functional Severity (CCFS) and with the measurements obtained using two validated evaluating systems, i.e., the Nine Hole Pegboard test (9HPT) and the Click Test. We also observed high internal consistency and an excellent intra-rater and test-retest reliability. We found a small Standard Error of Measurement (SEM) and an excellent Minimal Detectable Change (MDC), indicating that even small variations in the 15-WDACT measurements are to be associated with real changes in performance.
conclusionsWe have concluded that 15-WDACT is an easy, fast and reliable tool to assess the severity of the upper limb ataxia in patients with CA.
