Four Major Algorithms Used to Assess Potential Associations Between Olaparib and AEs.

Algorithms Equation Criteria
ROR ROR=ad/b/c lower limit of 95% CI>1, N≥3
95%CI=eln(ROR)±1.96(1/a+1/b+1/c+1/d)^0.5
PRR PRR=a(c+d)/c/(a+b) PRR≥2, χ2≥4, N≥3
χ2=[(ad-bc)^2](a+b+c+d)/[(a+b)(c+d)(a+c)(b+d)]
BCPNN IC=log2a(a+b+c+d)/((a+c)(a+b)) IC025>0
95%CI= E(IC) ± 2V(IC)^0.5
MGPS EBGM=a(a+b+c+d)/(a+c)/(a+b) EBGM05>2
95%CI=eln(EBGM)±1.96(1/a+1/b+1/c+1/d)^0.5

Notes: Equation: a, number of reports containing both the target drug and target adverse drug reaction; b, number of reports containing other adverse drug reaction of the target drug; c, number of reports containing the target adverse drug reaction of other drugs; d, number of reports containing other drugs and other adverse drug reactions.

Abbreviations: 95% CI, 95% confidence interval; N, the number of reports; χ2, chi-squared; IC, information component; IC025, the lower limit of 95% CI of the IC; E(IC), the IC expectations; V(IC), the variance of IC; EBGM, empirical Bayesian geometric mean; EBGM05, the lower limit of 95% CI of EBGM.
