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
Novel therapeutic approaches, such as exosome therapy, have garnered considerable attention for the treatment of central nervous system (CNS)-related disorders. This study aimed to investigate the effect of Neural stem cell-derived exosomes(Exo-NSC) on improving behavioral, molecular, and electrophysiological symptoms. Rats were divided into: control, lesioned groups (Alz, Alz + saline), treatments (Alz + NSC, Alz + Exo-NSC). the nucleus basalis of meynert (NBM) was lesioned using electrical lesion. One week after lesion, saline, NSC, and Exo-NSC were injected into the NBM. Twenty-eight days post-injection, behavioral tests (passive avoidance memory and locomotor activity) and EEG recordings were conducted. Subsequently, hippocampal levels of brain-derived neurotrophic factor (BDNF) and acetylcholine (ACh) were measured. NBM lesioning significantly reduced the step-through latency (STL), decreased alpha and gamma wave frequencies, increased theta and delta wave frequencies, and reduced Ach and BDNF levels compared to the control group. The NSC injection resulted in decreased delta wave frequency, increased gamma wave frequency, and elevated BDNF levels. Meanwhile, Exo-NSC injection significantly increased STL, beta and gamma wave frequencies, and levels of ACh and BDNF compared to lesioned groups. Overall, the findings indicate that Exo-NSC injection may be more effective than NSCs in improving passive avoidance memory. This benefit may stem from elevated hippocampal ACh and BDNF levels in the hippocampus.
