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: Opioid addiction is a major public health problem that causes impairments in cognitive and oxidative processes. The present study has been designed to investigate the therapeutic potential of aerobic exercise, combined with herbal supplements (Rosa Canina L, Matricaria recutita, and Berberis), on oxidative stress and spatial learning during morphine withdrawal. Materials and Methods: This trial consisted of 45 male C57BL/6 mice, divided into nine groups, with the induction of morphine dependence. Herbal supplements were combined with aerobic exercises for a 4-week intervention. Spatial learning was analyzed using the Morris Water Maze test; oxidative stress biomarkers were measured as superoxide dismutase (SOD), malondialdehyde (MDA), and total oxidative status (TOS); and gene expression levels of proenkephalin (PENK), prodynorphin (PDYN), and nuclear factor erythroid 2-related factor 2 (NRF2) were evaluated using real-time polymerase chain reaction (PCR). Results: Morphine-dependent mice exhibited impaired spatial learning and elevated oxidative stress. Herbal supplements and aerobic exercise, separately, enhanced spatial learning and antioxidant capacity, but the most significant benefits were seen when combined in reducing escape latency and improving SOD and TOS levels. Gene expression analysis revealed that the combination treatment brought PENK, PDYN, and NRF2 levels closer to those of the control group, suggesting synergistic neuroprotective effects. Conclusions: The combination of herbal supplements and aerobic exercise is promising in reducing oxidative stress and improving cognitive recovery during morphine withdrawal. These findings point to a holistic approach in addressing opioid addiction and may inform future clinical applications in improving rehabilitation outcomes and quality of life among affected individuals. Further research is needed to optimize these interventions for broader application.
