Abstract
The study included 1626 children, 26.4%(N:430) of the children
had a positive throat culture for group A B-hemolytic streptococci ,
42.3% were girls, 45.5% were above 5 years of age. The highest rate of
positive cultures was in children above 5 years of age (51.7%,p-value
=0.002).Each presenting sign and symptom was evaluated in terms of its
frequency and association with GABHS pharyngitis. The sensitivity,
specificity, PPV, NPV, LR+ve,and LR-ve were calculated for each sign
and symptom that was positively associated with GABHS Pharyngitis.
Multiple logistic regression analysis was used to develop our final clinical
prediction model.
