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

Background: Oral Lichen Planus (OLP) is a common inflammatory disease of unknown cause that knows also as a premalignant condition. Recent studies contributed nutritional factors to the pathogenesis of many autoimmune disorders. Objective: The aim of present study was to investigate the salivary levels of Magnesium (Mg), Calcium (Ca), Iron (Fe), Zinc (Zn) and Copper (Cu) in this disorder. Materials and Methods: In this observational case-control study, the unstimulated saliva of 40 patients with OLP and 40 age and sex matched healthy control subjects were collected. The salivary levels of Mg, Ca, Fe, Zn and Cu were determined using ICP-AES. Results: Mg levels were significantly lower in OLP patients than in healthy controls, although it didn’t differ significantly between erosive and non-erosive types of Lichen Planus. Also there was no meaningful relationship between the levels of Ca, Fe, Zn and Cu in case and control groups. Conclusion: Trace elements such as Mg may have a role in ethiopathogenesis of OLP.
