Visual acuity was converted to logMAR and its correlation with quantitative measurements of retinal, RPE, choroidal thickness and volume was done using t-test. Quantitative measurements at two separate visits 3 months apart were statistically analysed using Wilcoxon signrank test and a p value of <0.05 was considered statistically significant. Using the t-test and by comparing choroidal and retinal thickness with the fellow normal eyes, the correlation between study eyes (study group) and normal eyes (control group) was calculated. The ANOVA test was also used to compare the variance in means at different time points (two time points in this study), and also to analyse variance between study eyes and control eyes. Statistical analysis was performed using commercially available software (Intercooled STATA for Windows Version 13; Stata Corp). Data is presented in S2 Appendix .

For statistical analysis, eyes with VKH were considered as the study group and eyes from healthy controls were considered as the control group. Qualitative imaging data were analyzed with frequency and descriptive statistics. Quantitative CT measurements at two separate visits 6 months apart were analyzed statistically using the Wilcoxon sign rank test and a P value of <0.05 was considered statistically significant. Using the unpaired t-test and by comparing CT and CVI with the control group, the correlation between the study and control groups was calculated. The ANOVA test was used to compare the variance in means at two different time points, and also to analyze the variance in the means among study eyes and control eyes. Statistical analysis was performed using commercially available software (Intercooled STATA for Windows Version 13; Stata Corp, College Station, TX).
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.
