Systematic review and meta-analysis of the diagnostic accuracy of ultrasonography for deep vein thrombosis

11/ A systematic review of 22 cohorts compression = 94% sensitive for proximal DVT (distal 57%; duplex helps) Specificity 98% “Optimal sensitivity is achieved by using duplex or triplex, while optimal specificity is achieved by using compression alone” htt

@mellojonny @nedwards_1 @parthaskar -ve doppler has high sensitivity and specificity http://t.co/bGlPJygj, no role for aspirin though
