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

purposeThe aim of the present study was to evaluate the serum levels of trace minerals and heavy metals in obstructive sleep apnea (OSA) patients and to investigate whether there is a correlation between levels of trace minerals and demographic and biochemical variables.

methodsThis clinical, case-control study was performed on 61 OSA patients and 36 healthy controls. Demographic, radiological, biochemical variables, as well as serum levels of trace minerals (magnesium, copper, iron, zinc, manganese, cobalt) and heavy metals (lead, cadmium) were compared in OSA and control groups. In addition, correlation of serum levels of these substances to demographic, biochemical, and radiological parameters was tested.

resultsNot only serum levels of cholesterol, triglycerides, cadmium, cobalt, copper, iron, magnesium, manganese, lead, and zinc were found to be higher, but also carotid intima-media thickness (CIMT) was increased in OSA patients. Increase in CIMT was found to be correlated with levels of cobalt, copper, iron, magnesium, manganese, and zinc.

conclusionOur results have shown that serum levels of trace minerals and heavy metals were higher in OSA. This difference may ensource from deterioration of the balance of these substances due to oxidative stress and inflammation. Significance of these findings with respect to the etiopathogenesis, diagnosis, and treatment of OSA warrants further trials.
