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 Functional Dexterity Test (FDT) is a standardized assessment used to quantify dexterity, in-hand manipulation, related to function. Recommendations to modify the scoring have been proposed to eliminate penalties, adapt the test protocol, and change the outcome parameter. A new psychometrically sound scoring system has been used in the pediatric population; however, research in the adult population requires exploration. PURPOSE: The purpose of this study was to test if alterations in test administration, outcome recording, and outcome parameters show predictive validity for measured outcomes for age, ethnicity, and self-identified gender. The new method of administering the FDT eliminates penalties for improper performance and uses a score of speed derived from the timed score. It was theorized that eliminating assessment of reported errors in quality of movement in the quantitative scoring may improve the test validity. STUDY
designClinical Measurement.
methodsThe FDT was administered to 148 healthy adults aged between 18 and 78 years. No penalties were included in the quantitative scoring. Age, self-identified gender, ethnicity, and self-reported hand dominance were recorded. Time to complete the test was measured in seconds per usual protocol. The result was recorded as time and calculated as speed. Linear regression was performed to predict FDT speed from age, hand dominance, and self-identified gender.
resultsThe three predictors (age, hand dominance, and gender) associated with a linear decline in dexterity were significant (p ≤0.02). Dexterity showed a linear decline with age, and participants showed faster speeds with the dominant hand. Gender was a significant predictor of speed, with males having faster speeds by an average of 0.047 pegs per second (p = 0.01).
conclusionsScores using a simplified administration and speed as an outcome showed moderate predictive validity with age, gender, and the dominant hand used in this adult population. Future research exploring relationships with activities of daily living is needed.
