1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe overuse of compression ultrasound procedures on patients with suspected deep vein thrombosis compromise the cost-effectiveness of deep vein thrombosis management and emphasize room for improvement of the current diagnostic algorithm. As the complement system and hemostasis are comprehensively intertwined, we aimed to investigate complement activation products as diagnostic tests for acute deep vein thrombosis alone or together with D-dimer.

methodsWe performed a cross-sectional study using consecutive sampling of outpatients referred to the emergency department with suspected first-time deep vein thrombosis of the lower limbs, to investigate the diagnostic utility of the index tests C3bc and C5b-C9 terminal complex (TCC) with compression ultrasound as reference standard. For comparison of receiver operating characteristics, analyses were also performed for D-dimer and C-reactive protein in addition to analyses for the index tests on a D-dimer positive patient subgroup.

resultsOf the 366 included patients, 103 had deep vein thrombosis. The calculated effect sizes of differences between groups (Cohen's d) with 95% confidence intervals (95%CI) were 0.25 (95%CI 0.03-0.48) for C3bc, 0.33 (95%CI 0.09-0.57) for C5b-C9 terminal complex (TCC), 0.88 (95%CI 0.61-1.15) for C-reactive protein, and 1.64 (95%CI 1.37-1.91) for D-dimer. The areas under the curves derived from comparison receiver operating characteristics analyses with corresponding 95%CIs for C3bc, C5b-C9 terminal complex (TCC), C-reactive protein and D-dimer were 0.56 (95%CI 0.50-0.63), 0.64 (95%CI 0.58-0.69), 0.73 (95%CI 0.67-0.79) and 0.92 (95%CI 0.89-0.95), respectively.

conclusionThe plasma levels of the complement activation products C3bc and C5b-C9 terminal complex (TCC) were elevated in patients with acute deep vein thrombosis but displayed low diagnostic performance for deep vein thrombosis alone or together with D-dimer.
