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

Cirrhosis is characterized by a complex coagulation defect leading to the prolongation of the prothrombin and activated partial thromboplastin times (PT and APTT). Arbitrary PT cut-off values are still used as a yardstick to guide treatment with fresh-frozen plasma (FFP) or other pro-coagulant agents in patients undergoing invasive procedures. No randomized studies on the FFP efficacy are available, and are unlikely to be carried out because of their complex organization. An interim solution could be to evaluate the in vitro thrombin generation in plasmas from patients with cirrhosis when mixed with appropriate amounts of pooled normal plasma (PNP). The PT, APTT and thrombin generations in the presence of thrombomodulin were examined in 58 patients with cirrhosis and 24 healthy subjects both before and after mixing their plasmas with PNP at a proportion of 4 + 1 (patient + PNP), chosen to mimic in vivo conditions when patients are treated with 10 ml/kg of FFP. The PT and APTT, which were abnormal in the majority of unmixed patient plasmas were shortened considerably, but did not normalize completely when mixed with PNP. Thrombin generation, which was already within normal limits in all unmixed patient plasmas, remained essentially unchanged after mixing with PNP. In conclusion, thrombin generation in patients with cirrhosis does not appreciably change after in vitro addition of PNP despite PT and APTT shortening would suggest otherwise. These results question the validity of the PT as a stand-alone test to guide transfusion of FFP in the setting of chronic liver disease.
