Successful Treatment of Delusional Infestation with Olanzapine Depot.
Article in Alpha psychiatry, 2021. 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
Delusional infestation (DI) is a rare psychiatric disorder characterized by a persistent false belief that one is infected with nonliving or living pathogens, usually accompanied by formication. Other psychotic features, such as disorganized speech or hallucinations unrelated to the core delusion itself, are never present, and the delusional belief does not extend into other areas of life. Secondary DI, when one needs to address the underlying condition in order to achieve adequate treatment, is also possible. We present the case of a 42-year-old male with a 2-year history of having a persistent and firm belief that his house was infested with tiny insects that were constantly biting him and laying their eggs under his skin. His delusional belief was preceded by a complex, years-long substance use disorder, which confronted us with a differential diagnostic dilemma between primary and secondary DI. He was successfully treated with olanzapine pamoate depot, which was introduced to address his lack of insight and unsatisfactory compliance, and his delusion faded away after his symptoms subsided.
