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
backgroundThe cabbage stem flea beetle (Psylliodes chrysocephala) is a key pest of winter oilseed rape (OSR, Brassica napus); larval stages develop by feeding on petioles and stems during winter. Larval infestation may be influenced by plant traits and cropping systems. This study investigates the effects of OSR genotype and cropping system on larval infestation through specific ecophysiological traits and their interactions. In a field trial with four replicates, three OSR varieties (Mambo, Feliciano, and Angelico) were cultivated as monocrops or were sown with faba bean (Vicia faba) companion plants. Ecophysiological traits (morphological and metabolic) and P. chrysocephala larval infestation were assessed using a two-phase analysis combining direct relationship analysis and a regularized structural equation model.
resultsThe varietal factor had a greater influence on larval infestation than companion planting in this experiment. Larval infestation correlated positively with plant fresh weight, glucoraphanin, and butyl glucosinolate (butyl-GLS), and negatively with glucobrassicanapin concentration. The ecophysiological traits of Angelico, with lower concentration of glucoraphanin and butyl-GLS, explained its moderate decrease in larval infestation compared to Mambo. The ecophysiological traits of Feliciano, with a higher concentration of glucobrassicanapin and lower concentration of glucoraphanin and butyl-GLS, partially explained the resistance effect of this variety compared to Mambo. Contrary to expectations, companion planting slightly increased larval infestation, particularly in Mambo. This may be due to greater plant biomass under companion planting conditions rather than a direct effect of the companion plant on infestation rates. However, OSR grown with companion plants expressed greater concentration of glucobrassicanapin and a reduction in glucoraphanin, which may result in an indirect negative effect on the larval infestation.
conclusionThe variation in P. chrysocephala larval infestation in OSR plants may be partly explained by an interplay of specific concentrations of GLSs and morphological traits such as plant biomass. © 2026 The Author(s).
