Article in JPEN. Journal of parenteral and enteral nutrition, 2024. 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
backgroundEnteral feeding pump systems deliver decreased amounts of macronutrients in human milk to neonates. This study determined the macronutrient loss associated with a bottle-feeding pump system and the effect of manually mixing the human milk during extended feeds.
methodsMacronutrient content from samples of donor human milk was analyzed after simulated extended feeds with a bottle-feeding pump system, using a human milk analyzer. Simulations were repeated using manual mixing of the bottle every 30 min during feeding. The percentage of the baseline was calculated, and one-sample t tests and analysis of variance compared the effect of manual mixing and the duration of feeding on macronutrient delivery.
resultsThe delivery of fat and energy was lower over time, but manual mixing considerably improved retention. The length of feeding impacted fat delivery, with less fat delivered over time (P < 0.001). Manually mixing significantly increased fat delivery (P < 0.001). Similar results were found for energy, with a significant reduction in energy delivery over time (P < 0.001) and significantly more energy delivered with mixing (P < 0.001). Mixing and the duration of feeding had minimal effect on protein or carbohydrate delivery.
conclusionsBottle-feeding pump systems are associated with a significant reduction in the delivery of fat and energy of donor human milk. The manual mixing of donor human milk during prolonged feeds is a simple way to improve fat and energy delivery to the neonate.
