Prepulse inhibition of the startle reflex and response to antipsychotic treatments in two outbred mouse strains in comparison to the inbred DBA/2 mouse.
Article in Psychopharmacology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
rationaleNaturally low prepulse inhibition (PPI) in DBA/2 mice is increased by marketed antipsychotics and compounds acting at novel targets relevant to schizophrenia. Whether other mouse strains with naturally low PPI respond similarly and could be translational models of schizophrenia is unknown.
objectiveBaseline levels of PPI were determined in outbred CF-1 and Black Swiss mice. CF-1 and Black Swiss mice were then compared to DBA/2 mice for their responses to typical (haloperidol) and atypical (clozapine) antipsychotics and to compounds with potential antipsychotic activity, a histamine H(3) receptor antagonist (thioperamide) and a glycine transporter-1 inhibitor (SSR504734).
resultsCF-1 and Black Swiss mice had naturally low PPI, similar to the level in C57BL/6 mice, but higher than that in DBA/2 mice. Haloperidol (0.3-1 mg/kg) increased PPI in DBA/2, CF-1, and Black Swiss mice. Clozapine (3 mg/kg) increased PPI in DBA/2 and CF-1 mice, but not in Black Swiss mice. Thioperamide (10-30 mg/kg) and SSR504734 (30 mg/kg) increased PPI only in DBA/2 mice. Strain differences in PPI responsiveness were not due to differences in brain concentrations of the tested compounds.
conclusionsCF-1 mice with naturally low PPI may be useful for testing typical and atypical antipsychotics while Black Swiss mice only responded to a typical antipsychotic. DBA/2 mice remain the only strain with naturally low PPI that responds to marketed antipsychotics, as well as to compounds with novel mechanisms of action. Thus, DBA/2 mice may be the strain of choice for screening novel chemical entities for their ability to increase PPI.
