  • Upper panel shows median and interquartile ranges (IQR) for the seven static parameters in the diary. The right column shows the results of Friedman test for comparison between values of days 1–10, days 11–20 and days 21–30.

  • Lower panel shows results (expressed as median and IQR) for the reported effects of light conditions on the visual static. Each light condition was scored individually on a scale from 1 to 7. The right side of the table shows p values for Wilcoxon test comparing each light condition to the others, with significant results (p<0.008 following multiple comparisons correction) highlighted in bold.
