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
backgroundBotulinum toxin (BoNT) is a bacterial poison that acts by blocking the release of acetylcholine-containing vesicles at the neuromuscular junction. Notably, a mild amount of BoNT is known to exert therapeutic benefits against various diseases, including migraine, movement disorders, anxiety and neurocognitive deficits. BoNT treatment appears to increase platelet count in circulation. Therefore, BoNT treatment may be associated with the regulation of blood coagulation upon haemorrhagic events. However, the effects of BoNT on the degree of bleeding and clotting events have not yet been determined.
aimTo investigate the effect of BoNT on the bleeding parameters and blood coagulation events in experimental mice.
methodsA group of 7-8-month-old mice was intramuscularly injected with a mild single dose of BoNT. After a month of BoNT injection, animals were subjected to tail bleeding assay, assessment of clotting time, and degree of platelet aggregation in comparison with the control group.
resultsResults revealed that BoNT injection significantly reduced blood loss and bleeding time in experimental aging mice upon tail tip transection. Moreover, the blood samples collected from the BoNT-treated mice showed enhanced platelet aggregation and intense formation of the fibrin clot compared to the control. This study indicates a putative therapeutic value of BoNT in mitigating bleeding episodes, possibly through its platelet-enhancing property.
conclusionBoNT treatment effectively facilitates blood coagulation. Upon further validation, this approach can be translated to treat traumatic blood vessel injuries, haemorrhagic diseases, and bleeding complications associated with surgical procedures.
