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

aimsAsthma is one of the most common chronic inflammatory diseases of the airways. Calcitriol exerts its action through Vitamin D receptor (VDR), which is a high affinity nuclear receptor. VDR is a transcription factor that alters the transcription of target genes which are involved in a wide spectrum of biological responses. Lower serum vitamin D levels are associated with airway hyperresponsiveness and increased asthma severity. Prohibitin is a ubiquitously expressed protein localized to the cell and mitochondrial membranes and the nucleus. METHODS AND

resultsHBSMCs were cultured and treated with calcitriol and/or TNF-α. The mRNA and protein expression of prohibitin and VDR were analyzed using qPCR and immunoblotting, respectively. In the in vivo studies, female BALB/c mice were fed with special vitamin D-deficient or 2000IU/kg of vitamin D-supplemented diet for 13weeks. Mouse model of allergic airway inflammation was developed by OVA-sensitization and challenge. The expression pattern of TNF-α, prohibitin and VDR in the lung of OVA-sensitized mice was analyzed using immunofluorescence. Calcitriol significantly increased and TNF-α decreased the protein and mRNA expression of prohibitin and VDR in HBSMCs. There was significantly increased expression of TNF-α and decreased expression of VDR and prohibitin in the lung of vitamin D-deficient mouse model of allergic airway inflammation.

conclusionThese results suggest that under inflammatory conditions there is decreased expression of VDR resulting in decreased expression of prohibitin, which is a vitamin D target gene. Vitamin D deficiency causes increase in the expression of TNF-α, thereby increasing inflammation and decreases the expression of VDR and prohibitin. Supplementation with vitamin D might reduce the levels of TNF-α, thereby increasing the expression of VDR and prohibitin that could be responsible for reducing allergic airway inflammation.
