Sensitivity and specificity of different MRSA testing methodologies based on pooled data

MRSA testing modality	Number of studies	Sensitivity, % (95% CI)	Specificity, % (95% CI)
Culture 48 h	7	86.9 (74.7–93.7)	89.7 (77.7–95.6)a
Chromogenic media, 18–24 h	28	78.3 (71.0–84.1)a,b	98.6 (97.7–99.1)b,c
Chromogenic media, 48 h	24	87.6 (82.1–91.6)	94.7 (91.6–96.8)
PCR	15	92.5 (87.4–95.9)	97.0 (94.5–98.4)
