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

Thermal degradation of phytochemicals in heat-sensitive foods necessitates development of innovative drying strategies. This study investigated the application of dielectric barrier discharge (DBD) plasma pretreatment on intermittent microwave-hot air (IMHA) drying for beetroot slices. Scanning electron microscopy showed that DBD-plasma pretreatment generated surface microchannels and increased porosity by 27%, thereby facilitating moisture removal. The optimal conditions depended on the processing objective: the highest drying efficiency was achieved with 5 min of DBD-plasma pretreatment at 600 W and a pulse ratio (PR) of 1, reducing the total drying time by 34%, whereas the highest phytochemical retention was obtained at 180 W and PR of 2, yielding 55.2% higher betacyanin content, 33.8% greater antioxidant activity, and 43.7% higher total phenolic content. These findings highlight the potential of integrating DBD-plasma pretreatment with IMHA drying to improve drying efficiency and preserve product quality. From an industrial perspective, this approach may support the production of dried beetroot with improved functional quality and shorter processing time. A limitation of this study is that the process was evaluated at laboratory scale; therefore, further pilot-scale validation is required to confirm scalability.
