Figure 2

NOS2 deficiency does not alter IOP. The IOP distributions of mice of each genotype overlap extensively. The boxes show the upper and lower quartiles and the bars show the extremes including outliers. The centerline of each diamond is the mean with the upper and lower points of each diamond representing the 95% confidence intervals of the mean. Mean ± s.e.m in mm Hg, number of eyes examined; 3.5 months, Nos^+/+ 12.6 ± 0.24, 18; Nos^+/- 11.9 ± 0.30, 19; Nos^-/- 12.2 ± 0.19, 19; P value for all comparisons > 0.08; 10–11 months, Nos^+/+ 21.9 ± 0.87, 39; Nos^+/- 21.0 ± 0.95, 32; Nos^-/- 23.6 ± 1.3, 30, P value for all comparisons >0.09.
