Comparison of Visual Function Metrics

Check if the same lab product or an alternative is used in the 5 most similar protocols
SPSS versions 19 and 22 (SPSS Corporation, Chicago, IL, USA) were used for statistical analysis. Pearson's χ 2 test was performed to compare frequencies. Most of the variables of the VF group were non-Gaussian distributed according to the Kolmogorov-Smirnov test for normality and Q-Q plots. Therefore, the results are reported as medians and 25th and 75th percentiles. Consequently, female and male subjects of the VF group were compared separately with the norm group using the Mann-Whitney U test. The significance level was set at α = 0.05.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
