Assessing infant sleep quality and arousals: comparison of wearable data with parent perspectives.
Article in Pediatric 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
backgroundInfant sleep is vital for development, yet current assessments rely on subjective parental reports, underscoring the need for more reliable, objective methods.
methodsA total of 104 infants (424 nights) were measured at home using a novel NAPping PAnts (NAPPA) wearable, with arousals detected across a wide range of duration criteria. Parental sleep diaries were collected to capture perceived sleep quality (pSQ), reported arousals, and whether the infant slept in a shared or separate room. Diary data were used to study correlations with NAPPA-measured infant arousals, and regression models assessed the relationship between pSQ and reported versus measured arousals.
resultsThe pSQ correlated moderately with both the reported (ρ = -0.47, p < 0.001) and NAPPA-measured (ρ = -0.40, p < 0.001) arousals. The number of reported arousals was most comparable with the NAPPA-measured arousals in the 3-5-min duration range. However, parents significantly underestimated shorter arousals and overestimated longer ones, especially in a shared room with parents.
conclusionDirect infant measurements with the NAPPA wearable revealed a substantial difference between directly measured and parentally reported arousals. The findings suggest that infant sleep studies should incorporate direct and objective infant measurements, now made feasible and scalable through novel at-home wearable methods. IMPACT: Infant sleep assessments typically rely on parent's subjective reports rather than objective measurements of the infant's sleep. This study addresses a critical gap by comparing parental reports of infant sleep with high-resolution, objective measurements from the novel NAPPA (NAPping PAnts) wearable, demonstrating its feasibility for at-home use. Specifically, we show that parentally reported nighttime events, such as sleep quality or infant arousals, only partially reflect the infant's actual sleeping behaviour. Our findings highlight the importance of measuring infant sleep objectively, and the novel methodology opens new research avenues that may guide sleep health interventions.
