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

introductionChronic obstructive pulmonary disease (COPD) patients have increased risk for cardiovascular mortality and venous thromboembolism. Tissue factor (TF) is the physiological initiating mechanism for blood coagulation and is pro-inflammatory.

methodsWe have studied circulating blood-borne TF-procoagulant activity (TF-PCA), plasma coagulation factors (F) VIIa and FVIII, and thrombin-antithrombin (TAT) complexes in 11 stable, moderate-severe COPD patients, 10 free of exacerbation for >3 weeks.

resultsTF-PCA was increased in COPD patients (52.3+/-5.6 U/ml, (SE)) compared to control subjects (20.7+/-1.5, n=45, p<0.0001). TAT levels were increased (COPD patients: 2.99+/-0.65 ug/l; control subjects: 1.31+/-0.13, n=53, p<0.0001), indicating enhanced thrombin generation. Plasma FVIIa (the activated form of FVII) was higher in COPD (83+/-11 mU/ml; controls, 64+/-5 mU/ml, n=20) but did not reach statistical significance. Plasma FVIIc and FVIII were not increased. TF-PCA levels were inversely related to plasma FVIIa (r=-0.80, p=0.003) and FVIIc (r=-0.76, p=0.007).

conclusionsBlood-borne TF-PCA is elevated and constitutes a prothrombotic and proinflammatory state in stable but moderate-severe COPD, and may contribute to the increased risk for vascular events.
