Multidimensional analysis of floral scent emission patterns in Phalaenopsis 'Chanel'.
Article in BMC plant biology, 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
Phalaenopsis spp. is known as the best-selling potted flower in the world, while only a few cultivars possess floral scent, and the analysis of floral scent emission is limited. In present study, Phalaenopsis ‘Chanel’ with sweet and pleasant floral scent was used to explore the floral scent emission pattern by gas chromatography-mass spectrometry (GC-MS). A total of 21 VOCs were detected in blooming flowers, among which monoterpene linalool with an exceptional odor activity value of 1443.5 was identified as the vital VOC determining the aromatic profile of Phal. ‘Chanel’. The scent emission of Phal. ‘Chanel’ was multi-dimensionally regulated by spatial distribution and temporal dynamics. The scent emission pattern in spatial distribution was that the highest concentrations of both total VOCs and linalool were localized within the labellum, identifying it as the most fragrant floral structure. In the temporal dynamic pattern, the scent emission varied with floral development and circadian rhythm, and peaked in the bloom stage, especially on the 5th day after bloom (DAB) between 9:00 am and 11:00 am. Overall, the floral scent emission in Phal. ‘Chanel’ was dominated by linalool, and exhibited the spatiotemporal dynamics.
