Is There a Relationship Between Secondary Metabolites of Leaves and the Growth of Eucalyptus Species?

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
Flavonoids are essential molecules that affect plant growth and development and act as defense mechanisms against biotic and abiotic factors. This study aimed to assess whether the content of flavonoids in different species of Eucalyptus is related to tree growth. The objective of the work is (i) to identify whether there is a relationship between flavonoids, height and diameter among Eucalyptus species and (ii) to identify differences in flavonoid content between species. The experimental design was randomized blocks with three replicates, with 20 plants in each experimental plot. The treatments consisted of six Eucalyptus species: Eucalyptus camaldulensis, E. saligna, E. grandis, E. urophylla, C. citriodora and a GG100 clone (hybrid clone of E. urophylla × E. grandis). This study measured plant diameter at breast height (DBH) and height (HC). Leaf samples were taken from the species in their respective repetitions for flavonoid evaluation, and subsequent separation and quantification of the isoflavones, daidzein (D1), daidzin (D2), genistein (G1), genistin (G2), using liquid chromatography. In general, the E. grandis species showed the best results for DAP and AP. D1 was higher than what? for C. citriodora and E. saligna. D2 was higher than what? for E. camaldulensis. The principal component analysis demonstrated a negative relationship among the variables AP and DAP with D1, D2, G1, and G2. With the results of this study, it can be inferred that there is no relationship between height, diameter, and flavonoids among the Eucalyptus species evaluated since the species with the lowest concentrations of isoflavones had the highest growth and diameter.
