“…Inferential analysis was then carried out by carrying out the following procedures: Using a 2 × 2 contingency table, the different criteria were compared for identification of inappropriate medications (present or absent) and overall intracriteria concordance. The intraclass correlation test was applied to determine the correlation among the criteria for PIM (absent or present) and the number of PIM according to the following values: 0.40–0.75 = acceptable to good, and >0.75 = excellent The χ 2 ‐test and Student's t ‐test were used to determine which criteria (Beers, STOPP, EU[7]‐PIM and Taiwan) were associated with the presence or absence of falls, hospitalizations and cognitive impairment. Sensitivity, specificity, positive predictive value and negative predictive value of each criterion in identifying falls, hospitalizations and cognitive impairment were assessed as done in previous studies based on the following formulae: leftSEN=TP/TP+FNSPC=TN/TN+FPPPV=TP/TP+FPNPV=TN/TN+FN …”

“…Sensitivity, specificity and predictive values (positive and negative) of IgM antibodies were determined using MEIA, ELFA and IFAT and of IgA antibodies using a capture ELISA to diagnose congenital toxoplasmosis. Calculations were made using Thomas Bayes's mathematical formulas (Kawamura 2002).…”

“…Entretanto, sabe-se que conhecer a probabilidade de um indivíduo avaliado e com resultado positivo ser realmente doente (VPP) e a probabilidade de um indivíduo avaliado e com resultado negativo ser realmente normal (VPN) [36] é importante para a escolha do melhor preditor antropométrico de HAS.…”
