The authors studied 312 consecutive admissions to a psychiatric service for a relationship of the ABO - Rh blood groups with psychiatric diagnosis. Even though the results were significant, showing an increase of A blood group with M.D.D. and O group with Sch, the authors observe that the general patient population was skewed and significantly different from the general population of the area. This same observation was made for most of the previous studies that have reported significant correlations between various blood groups and different psychiatric diagnosis. Because of this, the conclusion of the present study is that at the present time positive associational findings of blood groups with psychiatric diagnosis are probably related to a skewed and stratified patient population sample.
作者对连续312例因ABO - Rh血型与精神疾病诊断关系而入住精神科的患者进行了研究。尽管结果具有显著性，显示重度抑郁症患者中A型血增多，精神分裂症患者中O型血增多，但作者观察到总体患者群体存在偏差，与该地区的总体人群有显著差异。之前大多数报道不同血型与不同精神疾病诊断之间存在显著相关性的研究也有同样的观察结果。因此，本研究的结论是，目前血型与精神疾病诊断之间的阳性关联发现可能与患者群体样本的偏差和分层有关。
