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
Aging is a worldwide socioeconomic burden. Cerebellar aging is an enigma contributing to many behavioral aging disorders, hence is its hindering by prophylactic measurements is a crucial geriatric research target. Red dragon fruit (RDF) is a tropical fruit with antioxidant, anti-inflammatory and anti-apoptotic properties. This study aimed to determine the protective effect of RDF extract against cerebellar aging. Thirty-two male albino rats were randomly allocated into 4 groups: Control, RDF, aged and RDF-aged groups. Aged group revealed structural distortion affecting cerebellar layers including a significant (P < 0.05) decrease in Purkinje cells number and decrease in granular cell layer thickness by comparison to the control and RDF groups. Additionally, distorted capillary endothelium, and defective myelination were noticed. Interestingly, cerebellar active caspase-3, iNOS, MDA and 3-NT and serum TNF-α levels significantly increased with aging by comparison to the control and RDF groups (all P < 0.05). Biochemical analysis revealed a significant (P < 0.05) decrease in cerebellar SOD and serum GSH levels in aged rats. RDF extract remarkably ameliorated most of the neuronal degenerative changes with a significant (P < 0.05) increase in Purkinje cells numbers, and granular cell layer thickness by comparison to the aged group. Furthermore, it resulted in a significant (P < 0.05) decrease in cerebellum expression of active caspase-3, iNOS, MDA, 3-NT, and serum TNF-α levels associated with a significant (P < 0.05) increase in cerebellar SOD and serum GSH levels by comparison to the aged group. To the best of our knowledge this is the first study showing a neuroprotective effect for RDF against cerebellar aging. RDF might be effective in attenuation of age-induced cerebellar degenerative changes through its anti-apoptotic, antioxidant and anti-inflammatory effects.
