Plant growth regulators enhance growth and photosynthetic performance in endangered Firmiana Kwangsiensis seedlings.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Firmiana kwangsiensis, a species endemic to China's Karst region, is listed as one of China's 120 key protected wild plants with extremely small populations. Climate change and human activities have severely restricted the survival and distribution of wild F. kwangsiensis communities, making urgent rescue and conservation measures imperative. To elucidate the growth-promoting mechanisms of plant growth regulators (PGRs) on F. kwangsiensis seedlings, a foliar spray experiment was conducted, and morphological, leaf, stem, and photosynthetic traits were measured. The results showed: (1) PGRs significantly enhanced morphological, stem, and photosynthetic indices, improved leaf traits, and promoted seedling growth and development; (2) Tight linkages existed between photosynthetic and growth traits in seedlings, with net photosynthetic rate (Pn) and chlorophyll content (measured as SPAD values) identified as key drivers of growth; (3) PGRs improved seedling quality by enhancing photosynthetic-growth interactions; (4) PGRs exhibited a "low-concentration promotion and high-concentration inhibition" effect, with highest growth observed under 100 mg·L
