While end-of-production sole-source lighting at a moderate intensity increased nutrient, water-soluble vitamin, and carotenoid content, the anthocyanin concentration of red leaf lettuce decreased.

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
In controlled environments, light intensity and quality can be manipulated to enhance beneficial phytochemicals, vitamins, and foliage color by increasing anthocyanin levels before harvest. Our objectives were to quantify whether a 50% reduction in end-of-production (EOP) light intensity, enriched with blue (B) light alone or with red (R) light, would yield red leaf lettuce of comparable or higher quality than that grown under high-intensity white light. Seedlings of red leaf lettuce (
