Effect of upright nesting position with swaddling on physiological status, sleep duration, and feeding tolerance in preterm infants in Indonesia: a quasi-experimental study.
Article in Child health nursing research, 2026. 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
purposeThis study examined the effects of upright nesting compared with swaddling on physiological status, sleep duration, and feeding tolerance in preterm infants in the neonatal intensive care unit.
methodsA total of 48 preterm infants, 24 per group, with gestational ages of 31 to 36 weeks, were enrolled. During the study, all infants were fed every 2 hours and did not receive sedation. Those requiring respiratory support or presenting with congenital abnormalities were excluded. At the unit level, participants were assigned to the "upright nesting" or the "swaddling" group. Physiological parameters, such as body temperature, oxygen saturation, heart rate, and respiratory rate, as well as sleep duration and feeding tolerance, were measured over 3 consecutive days. To examine group effects, time effects, and group-by-time interactions, linear mixed models were applied.
resultsBaseline characteristics, including sex, birth weight, and gestational age, were comparable between groups. Infants receiving upright nesting showed higher mean body temperature and oxygen saturation, lower heart rate, longer sleep duration, and improved feeding tolerance. Linear mixed models presented significant main effects of time for temperature, oxygen saturation, and heart rate, while significant group effects were presented for sleep duration and feeding tolerance. Group by time interactions were not statistically significant, suggesting favorable trends without differential change over time.
conclusionUpright nesting supports physiological stability, promotes longer sleep duration, and enhances feeding tolerance in preterm infants. Furthermore, it is a promising supportive strategy in neonatal intensive care, but larger studies are needed to confirm the results.
