An acetate prodrug of a pyridinol-based vitamin E analogue.
Article in Pharmaceutical research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo investigate of an approach to stabilize a novel pyridinol based α-tocopherol analogue (1) as a prodrug by acetylation of its phenol moiety.
methodsBiochemical indicators of oxidative stress in mitochondria were utilized to gain insight into the cytoprotective mechanism(s) of compound 1 acetate. Oxygen free radical scavenging activity was measured using DCF probe in a cultured cell model system that had been placed under oxidative stress. Lipid peroxidation was examined both in a cell-free system and in oxidatively stressed cultured cells. The bioenergetic parameters of mitochondria were evaluated by measuring mitochondrial membrane potential (Δψ(m)) and the MPT.
resultsThe present results suggest strongly that the antioxidant efficacy of compound 1 can be improved by using it as a prodrug. The tested prodrug has shown to be activated as a function of time, presumably due to susceptibility to enzymatic hydrolysis, and exhibits an antioxidant effect in time-dependent manner, providing a compound that is more effective than α-tocopherol acetate with regard to all protective properties studied.
conclusionsAn effective approach to stabilize compound 1 was realized by using its acetate as a prodrug.
