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

backgroundStudies have implicated the serotonin (5-HT)(7) receptor in physiological and pathophysiological phenomena, including thermoregulation, central control of micturition and locomotion, regulation of circadian rhythm, sleep, and depression. Further, several antidepressant and antipsychotic drugs have high affinity for the 5-HT(7) receptor.

methodsWe examined the role of 5-HT(7) receptors in a rodent analogue of sensorimotor gating deficits in schizophrenia: phencyclidine (PCP)-induced disruption of prepulse inhibition (PPI) of acoustic startle. We used mice lacking the 5-HT(7) receptor due to a targeted inactivation of this receptor gene and the selective 5-HT(7) receptor antagonist SB-269970.

resultsSB-269970 did not affect either baseline PPI or PCP-disrupted PPI. There was no difference between 5-HT(7)(+/+) and 5-HT(7)(-/-) mice in startle reactivity or PPI regardless of prepulse intensity (74-82 dB), interstimulus interval (25-500 msec), or pulse intensity (90-120 dB). Nevertheless, disruption of PPI produced by PCP (10 mg/kg) in wild-type mice was reduced in 5-HT(7)(-/-) mice, although it was not affected by the 5-HT(7) antagonist SB-269970. By contrast, the PPI-disruptive effects of apomorphine (5 mg/kg) and amphetamine (7.5 mg/kg) were comparable in both genotypes.

conclusionsThe results indicate a partial role for the 5-HT(7) receptor in the glutamatergic PPI model of sensorimotor gating deficits in schizophrenia that is sensitive to atypical antipsychotics and no involvement of this receptor in the dopaminergic PPI model that is sensitive to typical antipsychotics. Thus, the 5-HT(7)(-/-) mice may provide a useful tool to study the role of 5-HT(7) receptor in the action of atypical antipsychotic drugs and schizophrenia.
