Changes in Nutritional Status Through Low-Lactose Processed Milk Consumption in Korean Adults With Lactose Intolerance.
Article in Clinical nutrition research, 2025. 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
This study was conducted to evaluate changes in hydrogen breath test results and nutritional improvements when Korean adults diagnosed with lactose intolerance consumed processed milk containing approximately 10 g of lactose continuously. Participants consumed 240 mL of intervention food daily for a month and visited the research institute before and after the intervention to undergo nutrient intake survey and hydrogen breath tests. Data from 32 participants, with a mean age of 52.9 years, were analyzed. Hydrogen breath tests showed a significant decrease in hydrogen levels at all but baseline and the first of five 20-minute intervals of expiratory hydrogen concentration measurements. The third and fourth measurements showed the most significant changes (p < 0.001). The gastrointestinal symptoms showed a decreasing trend. Nutrient intake analysis demonstrated significant increases in animal protein (p < 0.001), calcium (p < 0.001), percentage of energy from protein (p = 0.032), vitamin A (p = 0.032), and retinol levels (p = 0.023). Regarding dietary habits, significant improvements were observed in nutritional quotient variables, including nutritional score (p = 0.042) and balance (p = 0.034). This study suggests that the removal of lactose and dairy products is not necessary for individuals with lactose intolerance. Incorporating low-lactose processed milk into their usual diet might be a practical dietary management strategy.
