Answer #1

ANSWER

   C. ( 7.7 )

THE CALCULATION OF NNT ( NUMBER NEEDED TO TREAT ) IS DONE BY DIVING 1 (ONE) BY ABSOLUTE RISK REDUCTION ASSOCIATED TO IT.

IN THE GIVEN SCENARIO WITH THE USE OF ANTIBIOTICS THE RISK IS GETTING REDUCED FROM 15 % TO 2 %, AND THE ARR ( ABSOLUTE RISK REDUCTION ) IS

HERE, ABSOLUTE RISK REDUCTION IS  

15 % - 2 % = 13%

SO,    THE ABSOLUTE RISK REDUCTION (ARR) IS    13 %

SIMPLIFYING 13 % = 0.13

NOW, APPLYING THE FORMULA NTT = 1 / ARR

NTT = 1 / 0.13

   NTT = 7.7

THIS MEANS THAT ON AN AVERAGE ONE LIFE IS SAVED BY TREATING 7.7 PATIENTS.
