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.
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
We developed a new reddish-purple fleshed sweetpotato (RFSP) cultivar, 'Sakurahonoka', with high yield for processing use. Released in 2025, the most distinctive characteristic of Sakurahonoka is its flesh color. The dominant aglycone (anthocyanidin-moiety) of anthocyanin (aglycone) in Sakurahonoka is pelargonidin, which distinctly varied from the purple-fleshed sweetpotato (PFSP) cultivars, whose dominant aglycones were peonidin or cyanidin. Sakurahonoka demonstrated a higher marketable root yield than the two major PFSP cultivars in the Kyushu region of Japan: 'Ayamurasaki' and 'Murasakimasari'. Additionally, Sakurahonoka showed a higher resistance to sweetpotato foot rot disease than Ayamurasaki. Furthermore, the color of Sakurahonoka processed as fried chips and steamed paste was unique and brighter than that of the PFSP cultivars. Food manufacturers have found that Sakurahonoka is suitable as an ingredient in fried chips and boiled-diced sweetpotato. It can be processed into a paste; however, its steamed sweetpotato is fibrous and requires effort to be strained. Thus, Sakurahonoka is an epoch-making RFSP that improves the color variation in sweetpotato-processed foods.
