Altitudinal and Habitat-Dependent Morphological and Biochemical Variations in Crepidium acuminatum (D.Don) Szlach. in the Western Himalaya.
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
Crepidium acuminatum (D.Don) Szlach. is a medicinal orchid used in Ayurvedic formulations, such as Astavarga and Chyawanprash Rasayana. The present study assessed morphological and biochemical variations among diverse populations of C. acuminatum. The Thalkedar population exhibited maximum plant height, stem length, leaf length, and pseudobulb length. Similarly, the highest carbohydrate (root part 45.65 ± 1.52%) and flavonoid content (aerial part 2.09 ± 0.26 mg QE/g) were recorded in the Pandukholi population. Maximum protein (aerial part 4.28 ± 0.32%) and phenolic content (root part 2.13 ± 0.15 mg GAE/g) occurred in the Thalkedar population, while the highest methionine content (root part 9.86 ± 0.25%) was observed in the Ramgarh population. Correlation analysis revealed significantly positive relationships (p < 0.05) among traits, including pseudobulb length with plant height (r = 0.804), and pseudobulb width with stem length (r = 0.789). Elevation also showed a strong positive correlation with protein content (r = 0.887) and phenolic content in aerial (r = 0.873) and root parts (r = 0.878). The study identifies particular populations that need conservation and others with commercial potential. It concludes that developing conservation policies and domestication trials is vital for the management of this valuable species.
