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

Immature citrus with peel was enzymatically treated for production of a hydrolysate with enriched bioactive components and higher antioxidant activity. The effects of reaction factors, including enzyme concentration, reaction time, and temperature on hesperetin and naringenin contents, total phenolic content (TPC), and antioxidant activity were investigated using response surface methodology. The models were adequate, and the enzyme concentration, temperature, and time positively affected hesperetin and naringenin contents and TPC, but negatively affected DPPH radical scavenging capacity. The reaction conditions for maximizing hesperetin, naringenin, and total phenol production and ferric reducing antioxidant power were optimized with the combination of enzyme concentration at 4%, 51 °C and 18 h. The hydrolysate at the optimized conditions contained higher hesperetin and naringenin contents and TPC compared with those before hydrolysis, by 251.7-, 45.5-, and 2.6-fold, respectively. This hydrolysate can be utilized in the production of functional beverages with high added values.
