# Positive results of OR are non-effective management. An OR ranging from 0.9 to 1.1 indicates that the public health services in the two groups are equal. A value of 1 represents perfect equality. ORs ranging from 0.7 to 0.8 or from 1.2 to 1.4 indicate relative equal. ORs ranging from 0.4 to 0.6 or from 1.5 to 2.9 indicate relatively unequal. ORs beyond 0.3 or 3.0 indicate totally unequal.
