Figure 1.
Pain threshold (left panel) and pain tolerance (right panel) in seconds when 24% w/v sucrose (solid bars) or water (hatched bars) was held in the children’s mouths during the CPT. Children were divided into two groups based on their most preferred level of sucrose: those who preferred sucrose concentrations below that used in the CPT and those who preferred levels equal to or greater than 24% w/v sucrose. Data are presented as geometric means ± geometric standard errors (GeoSEs). Notice that the upward-deflecting GeoSEs are greater than the downward-deflecting GeoSEs (see Data Analysis for explanation). a values are significantly different from b at the P<0.05 level.
