Hits	25/70	32/70	32/70	36/70	36/70
Overestimates	0/70	9/70	3/70	17/70	17/70
Underestimates	45/70	29/70	35/70	17/70	17/70

The first two rows report the odds of Overestimates (first row) an Underestimate (second row) with respect to the Hits at the average Mean IOP value. The third and fourth rows report the logit coefficients for Over and Underestimate for the Mean IOP Fluctuation value (i.e. how the odds vary with the real IOP Fluctuation value). Asterisks represent the significance level according to the legend in the footnotes. The second half of the table reports the actual Hits, Over and Underestimate counts for each strategy
