FIG 3. Bar graph shows values that represent the ratio of the RD in each group on each point to that on day 0 and represent mean ± SD.

A, Preventive effect of UV on the development of vasospasm among different treatment groups on day 2. UV treatment significantly inhibited vasospasm (P < .001 compared with the VS + fiber group). Bar graph shows that the preventive effect on vasospasm was not due to manipulation (VS + fiber group) but to UV irradiation (VS + UV group). *, P < .05 compared with the VS + fiber group.

B, Time course of %RD among different treatment groups.
