1 · What the graph read from it

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.

2 · The registry

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

rationalePhosphodiesterases (PDEs) belonging to the PDE4 family control intracellular concentrations of cyclic adenosine monophosphate (cAMP) by catalyzing its hydrolysis. Four separate PDE4 genes (PDE4A, PDE4B, PDE4C, and PDE4D) have been identified. PDE4 has been reported to be involved in various central nervous system (CNS) functions including depression, memory, and schizophrenia, although the specific subtype mediating these effects remains unclear.

objectiveTo investigate the role of PDE4B in the CNS, PDE4B wild-type and knockout mice (C57BL/6N background) were assessed in a variety of well-characterized behavioral tasks, and their brains were assayed for monoamine content.

resultsKnockout mice showed a significant reduction in prepulse inhibition. Spontaneous locomotor activity was decreased (16%) in knockout mice. Furthermore, when challenged with amphetamine, both groups of mice responded similarly to a low dose of d-amphetamine (1.0 mg/kg), but knockout mice showed an enhanced response to a higher dose (1.78 mg/kg). Decreases in baseline levels of monoamines and their metabolites within the striatum of knockout mice were also observed. PDE4B knockout mice showed a modest decrease in immobility time in the forced swim test that approached significance. In several other tests, including the elevated plus maze, hot plate, passive avoidance, and Morris water maze, wild-type and knockout mice performed similarly.

conclusionThe present studies demonstrate decreased striatal DA and 5-HT activity in the PDE4B knockout mice associated with decreased prepulse inhibition, decreased baseline motor activity, and an exaggerated locomotor response to amphetamine. These data further support a role for PDE4B in psychiatric diseases and striatal function.
