The postmortem activation status of platelets.
Article in International journal of legal medicine, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Platelets are activated by substances from the subendothelial matrix in endothelial lesions or by factors in the plasma coagulation cascade. Conversely, activated platelets are potent activators of this cascade. Only activated platelets express the adhesion molecules Gp53, GMP140 and thrombospondin on the plasma membrane. The postmortem activation status of platelets, therefore, can be determined immunoelectron microscopically by immunogold labeling of antibodies against these glycoproteins. Our studies revealed that the vast majority of these antigens were located within the granules postmortem, hence the platelets had not been activated. Thrombin-induced activation of platelets in vitro was only possible in the early postmortem interval, as demonstrated by labeling of the adhesion molecules on the plasma membrane. Later, such activation was no longer possible even though thrombin-induced fibrin formation gave the appearance of "coagulated blood". In forensic medicine, these findings can possibly be applied to distinguish intravital clotting from the postmortem coagulation phenomena and intravital hematomas from postmortem hematomas.
