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

C1-inhibitor (C1INH) was shown to enhance thrombin generation (TG) in the presence of thrombomodulin (TM) by reducing production of activated protein C. Because C1INH is known to inhibit fibrinolytic system proteases, the objective of this study was to evaluate the effect of moderate (3 IU/ml) and high (16 IU/ml) C1INH concentrations on TG and plasmin generation (PG) in the presence of TM. These concentrations were evaluated based on expected maximum plasma levels following C1INH replacement therapy and recently suggested supraphysiologic dosing. TG and PG were investigated in platelet poor plasmas obtained from 21 healthy donors. An assay designed to monitor the continuous generation of the 7-amino-4-methylcoumarin fluorescence from substrates specific to thrombin or plasmin was used to evaluate the impact of C1INH activity. To characterize the C1INH effects on TG and PG, the thrombin and plasmin concentration peaks and production rates were calculated. TM addition to donor plasma shifted the concentration dependence of C1INH on TG parameters from reduction to enhancement. Conversely, PG parameters were significantly reduced by 16 IU/ml in both the presence and absence of TM. Moderate C1INH concentration (3 IU/ml) reduced TG and PG in the absence of TM but did not significantly affect these parameters in the presence of TM. Finally, 3 IU/ml of C1INH reduced PG more so than TG in the absence of TM. The presented results suggest a mechanism by which C1INH could potentiate thrombosis by inhibition of fibrinolysis.
