I have collected data for 54 women who delivered by cesarean and having severe anemia( HB<10 gm/dl).All of them developed uterine atony during operation. In 21 women the atonic uterus were not recovered and hysterectomy was done.I want to know the association between low HB and persistent uterine atony . I run data in SPSS binary logistic regression but the odd ratio is <1

Could you help me to interpret the result or to direct me if I have to do other procedure.
