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

Mice carrying a conditional prothrombin knockout allele (fII(lox)) were established to develop an experimental setting for exploring the importance of thrombin in the maintenance of vascular integrity, the inflammatory response, and disease processes in adult animals. In the absence of Cre-mediated recombination, homozygous fII(lox/lox) mice or compound heterozygous mice carrying one fII(lox) allele and one constitutive-null allele were viable. Young adults exhibited neither spontaneous bleeding events nor diminished reproductive success. However, the induction of Cre recombinase in fII(lox) mice using the poly I:C-inducible Mx1-Cre system resulted in the rapid and near-complete recombination of the fII(lox) allele within the liver, the loss of circulating prothrombin, and profound derangements in coagulation function. Consistent with the notion that thrombin regulates coagulation and inflammatory pathways, an additional early consequence of reducing prothrombin was impaired antimicrobial function in mice challenged with Staphylococcus aureus peritonitis. However, life expectancy in unchallenged adults genetically depleted of prothrombin was very short ( approximately 5-7 days). The loss of viability was associated with the development of severe hemorrhagic events within multiple tissues, particularly in the heart and brain. Unlike the constitutive loss of either clotting or platelet function alone, the conditional loss of prothrombin is uniformly not compatible with maintenance of hemostasis or long-term survival.
