The median lowest MPD occurred at 96, 120, and 144 hours. This was not significant compared with 72 hours. The dark horizontal lines indicate median values; boxes, interquartile ranges; error bars, values adjacent to the interquartile ranges; and circles, outliers. There is no upper error bar at 96 hours because most of the results at 96 hours fell within the interquartile range. Likewise, there is no box at 48 hours because most of the results fell at the median value. Figure Legend:

For 15-minute immersion, most subjects were at peak response at 120 hours; for 5- minute immersion, they were at peak response between 96 and 144 hours. Figure Legend:

Broad peak was demonstrable from 72 to 168 hours. The dark horizontal lines indicate median values; boxes, interquartile ranges; error bars, values adjacent to the interquartile ranges; and circles, outliers. There is no upper error bar at 24 hours because most of the results at 24 hours fell within the interquartile range. Figure Legend:
