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 valorization of Camellia japonica flower varieties through the green extraction of their bioactive components is addressed. Microwave hydrodiffusion and gravity (MHG) can be an efficient and rapid pretreatment to dry the petals; for example, in the Royal Velvet variety, the energy consumption was 16 times lower compared to air drying. The hydrolates obtained in this stage represented only 0.5 mg gallic acid equivalents/g flower, but some of the fractions contained up to 10 times higher and a Trolox equivalent antioxidant capacity (TEAC) value equivalent to 0.4 g Trolox/g extract. The dried solids were extracted using 96% ethanol to yield around 30% solubles, which was 50% higher than the extraction yield from the air-dried samples. The MHG dried solids were treated with supercritical CO
