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 electromagnetic fields (EMFs) by wide range of the frequency spectrum, have capability to cause crucial alternation and deleterious effects in biological systems. The aim of the present study is to assay the biochemical components, enzymatic and non-enzymatic antioxidant systems of the electromagnetic fields treated samples of tea which is the most ancient non-alcoholic drink, containing different types of flavonols. Rutin, Quercetin, Myricetin, and Kaempferol as flavonoid components markers are also to be analyzed using high-performance liquid chromatography. The results show that The EMF's treatments brought about distinct alternations in biochemical components of tea, so that regardless of the intensity of the EMF's, less duration of exposure (30 min) caused more content of those mentioned flavonoid components (except Myricetin) than that of 60 min of exposure. A 30 min of 4 miliTesla (mT) exposure of the EMF's, resulted in the highest amount of Rutin, Quercetin, Myricetin, and Kaempferol. It is concluded that less duration of the EMF's treatments induces more production and also accumulation of enzymatic and non-enzymatic antioxidant components. In higher intensity of the EMF's (more than 4 mT), the concentrations of the mentioned biochemical components decreased.
