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

In the study, the morphological and structural properties of bunches and berries, as well as the chemical characterisation of three interspecific grapevine cultivars-'Bronner', 'Muscaris', and 'Morava'-were studied. Sugars and organic acids in the grapes were analysed using high-performance liquid chromatography (HPLC), while phenolic compounds were analysed by HPLC-mass spectrometry. 'Morava' and 'Muscaris' showed higher Hue angle values, indicating a greener skin coloration compared with 'Bronner', which exhibited a more yellow skin colour. 'Muscaris' and 'Bronner' had higher bunch weights than 'Morava', while the 100-berry weight did not differ significantly among the varieties. 'Bronner' must had the highest titratable acidity, and 'Muscaris' had the highest sugar content. Flavanols were the main phenolic compounds in the grapes, accounting for 76-88% of the total phenolic content. The highest concentrations of flavanols and caftaric acid were found in 'Bronner' and 'Muscaris' berries, while 'Morava' had the highest flavonol content. All studied varieties achieved good grape and must quality and are therefore recommended for wine production. 'Bronner' and 'Muscaris' stood out for their high bunch weight and high concentrations of flavanols and total phenolics, which contribute significantly to wine taste and overall quality. 'Muscaris' berries had a high sugar content, making this variety suitable for producing wines with higher alcohol content. In contrast, 'Bronner' is recommended for wines requiring higher acidity levels.
