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

rationaleReversal learning (RL), a type of executive function, dependent on prefrontal cortical function, is impaired in rodents by subchronic (sc) treatment with the N-methyl-D-aspartate receptor antagonist, phencyclidine (PCP), a widely studied model of cognitive impairment in schizophrenia (CIS).

objectiveThe principal objective of this study was to determine the ability of serotonin (5-HT)1A partial agonism and 5-HT7 receptor antagonism to improve RL in scPCP-treated mice.

methodsMale C57BL/6J mice were trained on an operant RL (ORL) task, then received PCP, 10 mg/kg, or saline, bid, for 7 days, followed by a 7-day washout period.

resultsscPCP significantly diminished the percent correct responding, increased total incorrect trials, and total incorrect responses, in the reversal phase performance of the ORL task. Pre-treatment with the selective 5-HT1A partial agonist, tandospirone, or the selective 5-HT7 antagonist, SB269970, but not the 5-HT7 agonist, AS 19, reversed the scPCP-induced deficit in RL. Pre-treatment with atypical antipsychotic drug lurasidone, which is a 5-HT1A partial agonist and 5-HT7 antagonist, as well as a 5-HT2A and dopamine (D)2 antagonist, also reversed RL deficit in the scPCP-treated mice. Furthermore, the selective 5-HT1A antagonist, WAY100635, blocked the ability of lurasidone to reverse the scPCP-induced RL deficit.

conclusionsThese results indicate that 5-HT7 antagonism and 5-HT1A partial agonism contribute to restoration of RL in scPCP-treated mice. It is suggested that these two mechanisms are effective in restoring RL by decreasing excessive GABAergic inhibition of cortical pyramidal neurons following withdrawal of scPCP treatment.
