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
Objectives: Chronic methamphetamine (METH) abuse is recognized as an important risk factor for cognitive impairment. A plant-based isoquinoline alkaloid, Berberine hydrochloride (BER), shows memory and cognition enhancement properties. Due to the aim of the present study which is to investigate the influence of BER administration on METH-induced cognitive deficits, we investigated neurotrophin signaling including brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) as a possible mechanism by which BER exerts its cognitive improvement influences. Materials and Methods: In this experimental study, thirty-two male Wistar rats were randomly classified into four groups, including non-treated control, intubated control, METH-inhaled, and METH-inhaled + BER-intubated. Rats in the METH-inhaled group underwent METH inhalation for 14 days, and the BER-inhaled and BER-intubated rats were intubated (100mg/kg) for the following three weeks. A novel object recognition task (NORt) was carried out on days 36 and 37. Rats were sacrificed for histological preparations after the behavioral tests. Neurotrophic factors, including GDNF and BDNF, were evaluated by immunofluorescence staining in the hippocampus. Results: This experiment indicated a dramatic improvement in cognitive deficits associated with chronic METH abuse ( Conclusion: Activation of neurotrophic factors after BER administration resulted in improvement of METH-induced cognitive deficits. Therefore, BER may be considered a promising treatment for METH users who experience cognition deficits.
