Effects of LED lighting on the nutritional properties and microbial safety of microgreens.
Review in Frontiers in nutrition, 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
Microgreens are immature and nutritious seedlings, rich in micronutrients and bioactive compounds these crops are commonly grown in controlled environments. Various light sources are used during indoor growth of microgreens depending on the specific light spectrum requirements of the crop, the energy efficiency of the lighting system, and budget-oriented market availability of production systems. Light Emitting Diode (LED) treatments offer a promising opportunity for microgreen production. This review synthesizes current literature on the effects of various treatments/conditions, emphasizing LED light spectra (wavelength), intensity, and photo period on microgreen characteristics including yield and growth, nutrient composition, and microbial safety. Currently, research on lighting effect on nutritional properties focus on Brassicaceae family which could be further expanded to other plant groups. Also, limited research on photoperiod (LED lighting duration) represents a research gap. Influence of the light quality, intensity and photoperiod have been reported on microgreen growth, yield and nutritional properties which vary with microgreen type. Although foodborne pathogens are known to persist and proliferate in microgreens under poor production and handling conditions, there remains a critical research gap regarding microbial survival, proliferation, and antimicrobial efficacy during production and storage under LED lighting systems. This highlights a need for comprehensive research to develop food safety protocols for microgreen production with LED light treatment holding significant potential.
