Lack of Antidepressant Effects of Low-Voltage-Sensitive T-Type Calcium Channel Blocker Ethosuximide in a Chronic Social Defeat Stress Model: Comparison with (R)-Ketamine.
Article in The international journal of neuropsychopharmacology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Background: A recent study demonstrated that low-voltage-sensitive T-type calcium channel blocker ethosuximide shows rapid antidepressant actions. This study was conducted to compare the antidepressant actions of ethosuximide and (R)-ketamine in a chronic social defeat stress model. Methods: Ethosuximide (100, 200, or 400 mg/kg), (R)-ketamine (10 mg/kg), or saline was administered i.p. to chronic social defeat stress-susceptible mice. Subsequently, locomotion test, tail suspension test, forced swimming test, and 1% sucrose preference test were performed. Results: (R)-ketamine showed rapid and long-lasting antidepressant actions in chronic social defeat stress-susceptible mice. In contrast, ethosuximide did not attenuate the increased immobility time of tail suspension test and forced swimming test in chronic social defeat stress-susceptible mice. In the sucrose preference test, ethosuximide did not improve decreased sucrose preference in chronic social defeat stress-susceptible mice. Conclusions: Unlike (R)-ketamine, ethosuximide did not show rapid and sustained antidepressant effects in a chronic social defeat stress model. Therefore, it is unlikely that low-voltage-sensitive T-type calcium channel inhibitors may have ketamine-like robust antidepressant actions.
