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

Phoradendron nervosum (hemiparasitic plant) exhibits remarkable metabolic plasticity, with significant variations in bioactive compound content, metabolite profiles, and antioxidant capacity depending on the host species (Laurus nobilis L., Hibiscus rosa-sinensis L., Populus alba L.) and organ type (leaves vs. fruits). A multi-method approach combining spectrophotometry, complementary antioxidant assays (ABTS, DPPH, FRAP), and complete metabolomic profiling by LC-MS was used to elucidate the biochemical interactions between P. nervosum and its hosts. The results obtained showed a differential distribution of total phenolic and flavonoid compounds, with leaves characterized by higher flavonoid concentrations (e.g., up to 0.286 mg QE/g DW). At the same time, fruits exhibited host-mediated modulations, especially in the species L. nobilis (e.g., the highest TPC at 2.723 mg GAE/g DW). Antioxidant activity was consistently higher in leaves (e.g., up to 41.26 µmol Trolox/g DW in DPPH assay), correlating with their enriched presence of phenolic acids and glycosylated flavonoids. The host species played a determining role in antioxidant capacity, as H. rosa-sinensis-associated plants exhibited the highest levels (e.g., 14.53 µmol Trolox/g DW in ABTS, 24.06 µmol Fe
