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
Objective: With the rise of industrialized dishes, the quality differences between industrial and traditional hand-cooked modes are a major concern for the food industry and consumers. This study examined the nutrient content variations in Chinese cuisines between these two cooking modes, addressing a crucial research gap. Methods: To account for moisture changes during cooking, water content in both raw ingredients and cooked dishes was adjusted, and nutrients were reported on a dry matter basis. The changes in nutrient content pre- and post-cooking were assessed by calculating the relative percentage of nutrient content in the cooked dishes in comparison to their levels in the raw ingredients. An independent Results: Macronutrient levels remained relatively stable, with changes of less than 20% across most dishes for both cooking methods, with some exceptions noted. Fat-soluble vitamins A and D exhibited minor fluctuations, ranging from 2.6 to 39.4%, while vitamin E levels consistently increased. In contrast, water-soluble vitamins, specifically B1, B2, B3, and B6, experienced substantial decreases across all examined dishes. The fatty acid profiles were consistent with the fat content, and mineral content demonstrated a moderate increase under both cooking conditions. An inter-group Conclusion: Among the six Chinese cuisines analyzed, the changes in nutrient content did not significantly differ between industrial and traditional cooking methods, with the notable exception of vitamin B6 retention. These findings contribute to a deeper understanding of how different cooking techniques impact the nutritional value of food, providing valuable insights for dietary decision-making and food processing technologies.
