Behavioral recovery profiling of cockroaches stung by the venomous wasp Ampulex compressa.

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
The parasitoid wasp Ampulex compressa injects venom into the brain of the American cockroach, targeting the central complex, a sensory-motor region. The venom induces grooming, followed by long-lasting hypokinesia. While grooming is attributed to dopamine in the venom, the mechanisms underlying hypokinesia remain unclear. Given the role of dopamine in modulating arousal and locomotion in insects, and our finding of long-term impairment in venom-induced grooming behavior, we hypothesized that the mechanisms behind long-term grooming impairments may provide insight into the mechanisms driving hypokinesia. We analyzed the recovery profile of venom-induced grooming in stung cockroaches and investigated dopamine receptor involvement through D1-like receptor agonist injections into the central complex. Our results reveal a deficient grooming response to a second sting 1 month after the first, and that this change is not caused by a lasting impairment of D1 receptor signaling but rather a complex interaction between venom components and the recovered brain.
