Characterization of Botanical and Geographic Origins of Blackthorn (Paliurus spina-christi Miller) Honeys From the Thrace Region of Türkiye.
Article in Chemistry & biodiversity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Blackthorn (Paliurus spina-christi Mill.), Thrace is a monofloral honey source. We characterized blackthorn honeys for botanical origin, physicochemical traits, antioxidant capacity, phenolic and amino acid profiles, volatiles, and minerals; flower extracts were also analyzed for markers. Melissopalynology identified 19/24 samples as monofloral (mean 81.6%). TPN10 averaged 53 411.87/10 g (normal quality). TPN10 correlated positively with diastase number (mean 21.11 DN; p < 0.05), aligning microscopic and chemical indicators. Total polyphenols (mean 637.65 mg GAE/kg), total flavonoids (10.18 mg QE/kg), and antioxidant capacity (FRAP 1.77 mg/mL; DPPH 16.06 mg/mL) were comparable to chestnut, pine, and oak honeys and reflected flower extract patterns. Phenolics (alloin A, abscisic acid, hesperidin, syringic acid) and amino acids (L-phenylalanine, L-tryptophan, L-asparagine) emerged as candidate biomarkers. Shared volatiles (benzoic and hexanoic acids, quinoline, 3-octanol) supported botanical linkage. Elemental means for Na, Mg, Al, K, Ca, and Fe (29.84; 24.44; 1.72; 2128.35; 76.26; 2.08 mg/kg) confirmed mineral richness.
