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

Combination-moderate electric field (MEF) processing successfully increases the iron content of kale by ~ 160 × as compared to untreated kale, but it is unknown whether this kale better delivers iron. It is also not known how combination-MEF treatments impact other nutritionally relevant bioactive kale compounds. This study aimed to (1) determine intestinal delivery of iron from the iron-enriched kale leaf following in vitro digestion and (2) assess ascorbic acid (AA), carotenoid, and α-tocopherol (i.e., vitamin E) concentrations in the combination-MEF treated kale. AA, carotenoids and α-tocopherol were separated and quantitated from non-polar kale extracts using high-performance liquid chromatography-diode-array detection (HPLC-DAD).
