relationship between blood group and skeletal malocclusion

If skeletal malocclusion subjects were found to have a high percentage of a certain blood type or RH when compared to the control group it will be reported that there is a relationship between blood group and skeletal malocclusion. If percentages of blood groups are approximately the same in the malocclusion subjects and the control then the investigator will report that there is no relationship between blood groups and skeletal malocclusion
