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 nutritional quality and amino acid profiles of 165 tomato samples (66 regular and 99 cherry varieties) from Beijing and Shandong in Northern China were assessed. The results showed that the regional origin was associated with differences in Dry Matter (8.88% vs. 6.73%), Soluble Solids (8.04% vs. 5.80%), total titratable acidity (5.57 vs. 4.08 g/kg), and Lycopene levels (67.32 vs. 38.22 mg/kg). Shandong tomatoes generally showed higher values than those from Beijing. Vitamin C levels were comparable between the two regions (17.79 vs. 13.98 mg/100 g), suggesting no linkage between Vitamin C variation and Dry Matter differences in this dataset. These regional differences likely reflect integrated effects of cultivation systems, varietal composition, and environmental conditions. They may not be explained by geographic origin alone. Principal component analysis revealed regional clustering driven by the accumulation of sugars, organic acids, and amino acids, with glutamate and aspartate contributing strongly to flavor-related variation. These findings provide insights into regional tomato quality and may support precision cultivation and breeding strategies.
