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
Posturography is a tool for quantitative measurement of balance in various static and dynamic test conditions. Current medical grade Posturography systems are very costly and rare outside research institutes. The Wii Balance Board is an inexpensive gaming device which works on similar principles and uses the center of pressure of an individual as an input for motion-controlled gaming. The aim of this study was to assess the validity of using a gaming platform (Wii Balance Board) as a substitute to medical grade Posturography machine. The objectives were to compare the measures of postural sway obtained from a gaming platform with those from a medical grade Posturography machine and to demonstrate a low-cost method of analysis of balance using the gaming platform. Descriptive Observational study. Individuals aged 18-65 years and having no apparent dysfunction of balance were assessed objectively using Wii Balance Board and Medical-grade Posturography machine. A program was developed in Scilab for computation of sway parameters. The results were compared in terms of correlation coefficient, Bland-Altmann plots, and ability to detect abnormal sway. A Pearson's correlation coefficient ranging from 0.53-0.91 was observed in various test conditions, with an overall value of 0.62 between the results of the two machines. The sensitivity was 69.39%, specificity was 73.16%, positive predictive value 24.29%, negative predictive value 95.07%, and accuracy 72.75%. Thus, we can conclude that the Wii Balance Board can be used as a low-cost substitute to medical grade Posturography machine for quantification of balance in situations where precise measurement of balance is not required.
