Persistent Facial Blanching after Botulinum Toxin Injection.
Article in Case reports in dermatology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
We report the case of a 38-year-old male patient who presented with blanching of the face after strenuous exercise or physical exertion. The symptoms regressed in a relaxed state. Three years before presentation, he underwent botulinum toxin injections in the affected areas of the face. Facial blanching is a rare side effect of botulinum toxin injection. The postulated pathophysiology involves different transmitters mainly acetylcholine as well as co-transmitters implicated in vasodilation. Usually, facial blanching resolves shortly after waning of the botulinum toxin. However, in our case, the symptoms persisted for a longer time. Till date, therapy options for post-botulinum facial blanching are lacking, mainly due to the temporary aspect of the disease.
