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

backgroundFraxinus mandshurica Rupr. is a key forest species in Northeast Asia, primarily distributed in semi-humid regions. Given its wide range of provenances, F. mandshurica exhibits substantial genetic and phenotypic variations. To identify drought–tolerant lines, we evaluated physiological, biochemical, and growth traits of two-year-old seedlings grown in a semi-arid environment across spring, summar and autumn.

resultsPrincipal component analysis (PCA) of 24 trait variables yielded 10 principal components per season, accounting for approximately 85% of the cumulative variation. We developed a comprehensive drought evaluation metric (D value) for each line by calculating weighted averages of PCA scores. Cluster analysis base on seasonal D values categorized 69 F. mandshurica lines into three groups: drought-tolerant, weak drought-sensitive, and drought-sensitive. Using two growth traits, these lines were further classified into high-, medium-, and low-growth groups. From this, we identified five elite lines combining drought tolerance and rapid growth. Stepwise regression revealed that F. mandshurica employs distinct drought-tolerance strategies across seasons.

conclusionsWe developled robust drought-tolerance evaluation models for F. mandshurica and selected five high-performing lines with dual traits of drought tolerance and fast growth. Our results provided a basis for afforestation efforts of F. mandshurica in semi-arid regions.
