1 · What the graph read from it

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.

2 · The registry

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

backgroundLight availability is a key ecological factor determining the growth and physiological acclimation of epiphytic orchids. To evaluate how Dendrobium fimbriatum responds to heterogeneous light environments, plants were cultivated under three relative light intensities (40%, 20%, and 8% of full sunlight). Growth traits, diurnal gas exchange, light-response parameters, chlorophyll content, leaf microstructural characteristics, and bioactive compounds were measured after five months of treatment.

resultsPlants grown under 20% light showed the best overall vegetative performance. Compared with 40% light, 20% light increased basal stem diameter and single-leaf area by 41.7% and 150.4%, respectively, and increased daily photosynthetic average (DPA) and maximum net photosynthetic rate (P

conclusionsD. fimbriatum manages environmental heterogeneity through highly coordinated trait adjustments rather than isolated responses. The 20% light optimized the balance between carbon gain and metabolic maintenance, maximizing vegetative performance. At 40% light, structural investment and secondary metabolite accumulation were enhanced, whereas 8% light promoted chlorophyll accumulation and shade-acclimation traits at the expense of maximal growth. These quantified trade-offs provide an empirical foundation for understanding the ecological resilience of epiphytic orchids and optimizing cultivation protocols.
