1 · What the graph read from it

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.

2 · The registry

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

backgroundOsteopontin (OPN) is an important breastmilk protein involved in infant intestinal, immunological, and brain development. However, little is known about how common milk pasteurization and storage techniques affect this important bioactive protein.

methodsHuman milk osteopontin concentration was measured in single-donor fresh (n = 1) or frozen (n = 20) breastmilk, pooled Holder-pasteurized donor breastmilk (n = 11), and a shelf-stable (retort pasteurized) breastmilk product (n = 2) by ELISA. Single-donor breastmilk samples were subjected to pasteurization and/or freezing before measuring osteopontin concentrations.

resultsHolder pasteurization of breastmilk resulted in an ∼50% decrease in osteopontin concentration within single-donor samples. Breastmilk from mothers of preterm infants trended toward higher osteopontin concentration than mothers of term infants; however, samples from preterm mothers experienced greater osteopontin degradation upon pasteurization. A commercial breastmilk product that underwent retort pasteurization had lower osteopontin concentration than a Holder-pasteurized pooled breastmilk product. Finally, freezing breastmilk prior to Holder pasteurization resulted in less osteopontin degradation than Holder pasteurization prior to freezing.

conclusionsCommonly used breastmilk pasteurization and storage techniques, including freezing and Holder pasteurization, decrease the concentration of the bioactive protein osteopontin in human breastmilk. Holder pasteurization reduced osteopontin concentration by an average of 63%, while freezing resulted in an 8-12% decrease. IMPACT: Pasteurization of human breastmilk significantly decreases the concentration of the bioactive protein osteopontin. Use of both pasteurization and freezing techniques for breastmilk preservation results in greater loss of osteopontin. This study presents for the first time an analysis of osteopontin concentrations in single-donor pasteurized milk samples.
