Multidimensional analysis of honey from Eastern Anatolia (Kars): Pollen spectrum, physicochemical properties, and antimicrobial activity.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study investigates the physicochemical properties, pollen composition, and antimicrobial activity of honey samples collected from Kars province, Türkiye. A total of 30 honey samples were analyzed for moisture content (13.9-18.0%), pH (3.44-3.92), electrical conductivity (0.138-0.343 mS/cm), free acidity (13.9-31.5 meq/kg), diastase activity (4.93-28.1 DN), hydroxymethylfurfural (HMF) levels (3.5-37.1 mg/kg), sugar profile (fructose: 32.8-41.0%, glucose: 26.2-32.6%, sucrose: 0.1-2.7%, maltose: 1.4-2.7%), and proline content (288.87-1272.9 mg/kg). Pollen analysis identified 52 taxa from 30 botanical families, with Fabaceae, Boraginaceae, Lamiaceae, Asteraceae, and Brassicaceae being the most dominant. Of the honey samples, 27 were classified as multifloral and 3 as unifloral. Total pollen counts per 10 g (TPC-10 g) of honey ranged between Group II and Group V categories (2000 to > 100000 grains). The antimicrobial activity of the honey was evaluated against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, and Bacillus subtilis using the agar well diffusion method. Inhibition zones ranged from 11 ± 0.55 mm to 24 ± 1.2 mm, with greater efficacy observed against Gram-positive bacteria. Significant correlations were found between diastase activity and Staphylococcus aureus (r = 0.704, p < 0.01) and Enterococcus faecalis (r = 0.518, p < 0.01), as well as between proline content and Klebsiella pneumoniae (r = 0.454, p < 0.05), Pseudomonas aeruginosa (r = 0.384, p < 0.05), Staphylococcus aureus (r = 0.439, p < 0.05), and Bacillus subtilis (r = 0.435, p < 0.05). The sugar composition complied with international standards, with fructose and glucose being the predominant sugars. HMF levels remained within acceptable limits, suggesting appropriate storage and processing conditions. Overall, the findings highlight the high quality and antimicrobial potential of Kars honey, supporting its value as a natural and functional food product.
