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

Multiple sclerosis is a chronic inflammatory neurodegenerative disease of the central nervous system which injures the myelin sheath. Telmisartan and nifedipine are antihypertensive drugs that recently showed neuroprotective properties against neurodegenerative diseases. This study evaluated the neuroprotective effect of telmisartan or nifedipine in cuprizone-induced demyelination in mice by examining the underlying mechanisms. C57BL/6 mice received a diet containing 0.7% (w/w) cuprizone for 7 days followed by 3 weeks on a 0.2% cuprizone diet. Telmisartan (5 mg/kg/day, p.o.) or nifedipine (5 mg/kg/day, p.o.) was administered for 3 weeks starting from the second week. Telmisartan or nifedipine improved locomotor activity and enhanced motor coordination as demonstrated by open field, rotarod, and grip strength tests. Furthermore, telmisartan or nifedipine restored myelin basic protein mRNA and protein expression and increased luxol fast blue-staining intensity. Telmisartan or nifedipine attenuated cuprizone-induced oxidative stress and apoptosis by decreasing brain malondialdehyde and caspase-3 along with restoring reduced glutathione and brain-derived neurotrophic factor levels. Telmisartan or nifedipine exerted an anti-inflammatory effect by reducing the expression of nuclear factor kappa B (NF-κB p65) as well as pro-inflammatory cytokines and elevating the expression of IκB-α. In parallel, telmisartan or nifedipine upregulated the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and the levels of heme oxygenase-1 and NADPH quinone oxidoreductase 1 enzymes. In conclusion, the current study provides evidence for the protective effect of telmisartan and nifedipine in cuprizone-induced demyelination and behavioral dysfunction in mice possibly by modulating NF-κB and Nrf2 signaling pathways.
