1 · What the graph read from it

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.

2 · The registry

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

Introduction: Creatine has been recognized not only as an energy buffer but also for its antioxidant, antiapoptotic, and anti-excitotoxic properties, making it of interest as a neuroprotective agent. Oral creatine monohydrate supplementation is ineffective due to poor brain and neuronal distribution and optimized forms of creatine deserve to be studied. Thus, dodecyl creatine ester (DCE), named CBT101, is a prodrug of creatine created for this purpose. When administered nasally it can follow the nose-to-brain pathway to deliver creatine to neuronal cells after passive diffusion across membranes. In this study, the therapeutic efficacy of intranasal DCE treatment was demonstrated in a 6-OHDA-intoxicated rat model, which is relevant to neurodegenerative diseases such as Parkinson's disease. Methods: 6-OHDA-intoxicated rats received DCE (13.3 mg/kg/day) or a vehicle intranasally for 5 weeks and were compared to a sham group. Imbalance in dopamine between the two hemispheres was assessed using the amphetamine-induced turning test after 3 weeks and sensorimotor performance using the beam walking test after 4 weeks, with ongoing treatment. Results and discussion: Five weeks after 6-OHDA intoxication, daily intranasal DCE treatment improved sensorimotor performance, striatal dopamine concentration, and modulated striatal pro-BDNF/BDNF balance and neurofilament expression both in plasma and in the striatum. These observations highlight DCE's potential as a therapeutic strategy for neurodegenerative diseases characterized by energy deficiency and major mitochondrial dysfunction.
