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
Antipsychotic drugs are the mainstay of psychotic disorders. The 'typical' antipsychotic agents are commonly employed for the positive symptoms of schizophrenia, though at an expense of extrapyramidal side effects (EPS). In the present study, we employed haloperidol (HP)-induced catalepsy model in mice to evaluate the role of adenosine receptor antagonist and cyclooxygenase (COX) enzyme inhibitor in the amelioration of EPS. HP produced a full blown catalepsy, akinesia and a significant impairment in locomotion and antioxidant status. Pre-treatment with COX inhibitor; naproxen (NPx) and adenosine receptor antagonist; caffeine (CAF), showed a significant impact on HP-induced cataleptic symptoms. Adenosine exerts pivotal control on dopaminergic receptors and is also involved in receptor internalization and recycling. On the other hand, prostaglandins (PGs) are implicated as neuro-inflammatory molecules released due to microglial activation in both Parkinson's disease (PD) and antipsychotics-induced EPS. The involvement of these neuroeffector molecules has led to the possibility of use of CAF and COX inhibitors as therapeutic approaches to reduce the EPS burden of antipsychotic drugs. Both these pathways seem to be interlinked to each other, where adenosine modulates the formation of PGs through transcriptional modulation of COXs. We observed an additive effect with combined treatment of NPx and CAF against HP-induced movement disorder. These effects lead us to propose that neuromodulatory pathways of dopaminergic circuitry need to be explored for further understanding and utilizing the full therapeutic potential of antipsychotic agents.
