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
backgroundSaffron, a valuable spice and industrial crop used in food, pharma, and cosmetics, is propagated only vegetatively via corms due to triploid male sterility. Corms are the primary storage organs and determine both the yield and quality of daughter corms. However, the optimal growing conditions for producing large, heavy daughter corms remain unclear. MATERIALS AND
methodsHere, we examined the effects of light spectra and plant growth regulators on photosynthetic pigments, starch accumulation, and daughter corm production in a two-stage system, with reproductive growth occurring indoors followed by outdoor maturation. The plants were grown under four light spectra: white, red, blue, and a combination of half red and half blue. Two plant growth regulators, gibberellic acid and gamma-aminobutyric acid, were applied during the reproductive stage of the plant. After flowering, the mother corms were directly transplanted to the field for the development of daughter corms.
resultsThe combination of red and blue light with gamma-aminobutyric acid produced the heaviest daughter corms, reaching 8.7 g dry weight, and the highest starch accumulation in the corms reached 383 milligrams per gram fresh weight. Red and blue light combined with gibberellic acid increased the leaf starch concentration to 926 milligrams per gram of fresh weight. A higher pigment content and larger leaf area support greater photosynthetic performance, preserve carbohydrate reserves in mother corms, and ultimately favor the production of heavier daughter corms.
conclusionsThese results provide practical insights for optimizing saffron propagation in controlled-environment and field systems, directly contributing to industrial-scale production and value chain efficiency. Future research should test dynamic light spectra and optimized regulatory strategies to refine corm development and strengthen commercial and industrial saffron production.
