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

backgroundLitsea cubeba is an important industrial plant valued for its pericarp essential oil and kernel oil. However, variation in seed traits and kernel oil characteristics among wild populations and their relationships with ecological factors remain insufficiently understood. Wild germplam from 21 provenances across eight provinces in southern China was evaluated for seed traits, kernel oil content, and fatty acid composition, and variance analysis, correlation and path analysis, and multivariate ecological analyses were used to characterize phenotypic diversity and examine its associations with environmental variables.

resultsAnalysis of variance showed that the investigated provenances differed significantly in seed traits and kernel oil characteristics (P < 0.05). Provenances ZJ-LY and SC-KJ exhibited relatively high kernel oil content (≥ 35%), whereas YN-XC, GZ-ZY, and SC-KJ showed higher seed yields (SY, ≥ 1000 g.tree

conclusionsThese findings reveal substantial variation in seed traits and kernel oil characteristics among wild L. cubeba populations in southern China. Provenances ZJ-LY and SC-KJ are promising candidates for breeding programs targeting high kernel oil content. Moreover, the identified associations of kernel oil accumulation and fatty acid composition with annual minimum temperature, soil water status, and soil nutrients provide useful guidance for germplasm selection and cultivation management.
