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
backgroundTissue culture optimization in orchids is constrained by the impracticality of experimentally testing all possible combinations of environmental and nutritional factors. In this study, the interactive effects of culture media composition, light quality, plant developmental status (rooted vs. rootless), and culture configuration (single-phase vs. two-phase) on organ-specific morpho-physiological traits of Phalaenopsis amabilis were investigated under in vitro condition. Growth variables, pigment composition, carbohydrate metabolism, and maximum quantum efficiency of photosystem II (F
resultsANFIS exhibited superior capability compared with FIS in predicting nonlinear response surfaces and identifying trait-specific optimal regions. For leaf growth traits, ANFIS predicted optimal regions under orange-red light combined with moderate nitrogen (N) availability, whereas FIS produced narrower and more localized optima. For root biomass and carbohydrate accumulation traits, ANFIS predicted red light dominated optimal regions with elevated phosphorus (P) and reduced N, indicating stronger sensitivity of sink-related traits to light nutrient interactions. For leaf pigment accumulation traits, ANFIS identified broader optimal regions under blue light with lower N levels, while carbohydrate related traits showed distinct optima under red and green spectral conditions depending on nutrient balance. Overall, ANFIS generated more distinct and physiologically consistent response surfaces than FIS across all traits.
conclusionsMachine learning assisted modeling effectively identified organ-specific optimal treatment regions and revealed complex nonlinear interactions among experimental factors that are not directly observable from mean treatment comparisons. The ANFIS framework provides a robust predictive tool for optimizing orchid tissue culture systems and for generating testable hypotheses for future in vitro propagation studies.
