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

The present study investigated the neuroprotective effect of curcuminoids, the active polyphenols of Curcuma longa (L.) rhizomes against inflammation-mediated dopaminergic neurodegeneration in the 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine (MPTP) model of Parkinson's disease (PD). Male C57BL/6 mice were pre-treated with curcuminoids (150 mg/kg/day) for 1 week, followed by four intra-peritoneal (i.p.) injections of MPTP (20 mg/kg) at 2 h intervals with further administration of curcuminoids or deprenyl (3 mg/kg/day) for 2 weeks. Our results show that oral administration of curcuminoids significantly prevented MPTP-mediated depletion of dopamine and tyrosine hydroxylase (TH) immunoreactivity. In-addition, pre-treatment with curcuminoids reversed glial fibrillary acidic protein (GFAP) and inducible nitric oxide synthase (iNOS) protein expression, as well as, reduced pro-inflammatory cytokine and total nitrite generation in the striatum of MPTP-intoxicated mice. Significant improvement in motor performance and gross behavioural activity, as determined by rota-rod and open field tests were also observed. Taken together, our findings suggest that curcuminoids exert a neuroprotective effect against MPTP-induced dopaminergic neurodegeneration through its anti-inflammatory action and thus holds immense potential as a therapeutic candidate for the prevention and management of PD.
