Influence of different breast expression techniques on human colostrum macronutrient concentrations.

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
objectiveTo evaluate the effects of breast expression methods on macronutrient and caloric concentrations in human colostrum. STUDY
designA cross-sectional study in which colostrum samples were collected simultaneously from each breast using different milk expression methods, including manual expression or electric pumping, assigned by simple randomization. Macronutrients were measured by infrared spectroscopy, and their concentrations were compared by the Wilcoxon test.
resultsNinety-six samples from each breast of selected donors were evaluated. There were no differences in carbohydrate (6.1 vs. 6.1 g/dL; p: 0.218) and protein (2.1 vs. 2.1 g/dL; p: 0.772) concentrations between the samples collected by manual expression and electric pumping. However, in those collected by manual expression, lipid concentrations (2.6 vs. 2.2 g/dL; p < 0.001) and caloric content (60 vs. 57 Kcal/dL; p = 0.001) were higher.
conclusionsColostrum collected by hand expression had a higher lipid concentration and caloric content than that collected by an electric pump.
