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
Nonneuronal cells mediate neurotransmission and drug addiction. However, the role of oligodendrocytes in stress-induced cocaine relapses remains unclear. In the present study, we investigated the role of the oligodendrocyte-abundant molecule crystallin alpha B (CRYAB) in cocaine-induced conditioned place preference (CPP) relapsed by restraint stress. RNA sequencing (RNA-seq) was performed to identify oligodendrocytes and stress-associated molecules in the nucleus accumbens (NAcc) of both drug users and cocaine-treated animals. Further, we studied which cell subtypes in the brain express CRYAB. The effects of stress hormones and cocaine on CRYAB expression were evaluated in vitro in human oligodendrocytes. CRYAB is upregulated in the NAcc of both cocaine-treated animals and drug users. CRYAB levels in the NAcc of mice increased during CPP development but decreased following stress-induced relapse. Interestingly, CRYAB is expressed in oligodendrocytes in the NAcc of mice. Extracellular CRYAB levels are regulated by cocaine and stress hormone treatments in oligodendrocyte cultures. Dopamine levels in the NAcc and CPP development of CPP are significantly increased by cocaine in CRYAB knockout (KO) mice. Further, we demonstrated that CRYAB binds to the excitatory amino acid transporter 2 (EAAT2) in the NAcc of mice treated with cocaine. We suggest that oligodendrocyte-derived CRYAB regulates dopamine neurotransmission and stress-evoked cocaine reward behaviour via the modulation of EAAT2 in the NAcc.
