SBP, DBP and PR before and after PFS according to class clusters. SBP: Systolic blood pressures, DBP: Diastolic blood pressures, PR: Pulse rates, and PFS: Pit and fissure sealant. The dots indicate the mean values, and I bars indicate the upper confidence value (mean plus 1.96 times the standard error) and the lower confidence value (mean minus 1.96 times the standard error). Those with green color represent values before PFS, and red indicate values after PFS
