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
rationaleNociceptin/orphanin FQ (N/OFQ) is the endogenous ligand of a Gi protein-coupled receptor named NOP. Both N/OFQ and NOP receptor are widely expressed in brain areas involved in the control of emotional processes. Clinical and preclinical studies support antidepressant effects due to the blockade of NOP receptor signaling. By contrast, NOP receptor activation did not evoke any change in behavioral despair tests.
objectivesThe present study aimed to investigate the effects of the co-administration of NOP agonists and classic antidepressant drugs in the forced swimming test (FST) and learned helplessness model (LH) in mice.
methodsMale Swiss mice were co-administered with NOP agonists (N/OFQ and Ro 65-6570) and antidepressants (nortriptyline, fluoxetine, and R-ketamine) or SB-612111 (NOP antagonist) and the behavioral effects were assessed in the FST and LH tests.
resultsFluoxetine, nortriptyline, R-ketamine and the NOP antagonist SB-612111 displayed antidepressant-like effects in the FST. The administration of the NOP agonists N/OFQ and Ro 65-6570 did not induce any behavioral change. However, co-administration of NOP agonists blocked the antidepressant effects of SB-612111, fluoxetine, and nortriptyline, but not R-ketamine in the FST. Similarly, in the LH, the systemic injection of SB-612111, nortriptyline, and R-ketamine reversed helplessness. The co-administration of Ro 65-6570 blocked the antidepressant-like effects of SB-612111 and nortriptyline, but not R-ketamine.
conclusionsNOP receptor activation inhibits the acute antidepressant effects of nortriptyline and fluoxetine, but not R-ketamine. The present findings contribute to further understand the role played by the N/OFQ-NOP receptor system in regulating mood states.
