Touchless monitoring of neonatal activity: a multi-center study.
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
backgroundNeonatal activity level is an important physiological parameter linked to lethargic response to over sedation, agitation associated with under-titration of pain medication or seizures and serves as an early indicator of disease onset.
methodsActivity was monitored continuously using a non-contact ("touchless") technology based on a depth sensing camera in 61 neonates from two sites (N = 32 'LA' / 29 'Utah'). Gestational age, mean (SD): 34.1 (3.3) weeks Utah, 34.7 (3.8) weeks LA. Time after birth 2.5 (2.5) weeks Utah, 1.6, (1.9) weeks LA. This was compared to manual observation of motion using two main random forest machine learning analyses: [1] combined data set leave-one-out cross-validation (LOOCV) on a per-neonate basis and [2] inter-site analysis.
resultsCombined analysis: mean [CI] sensitivity, specificity, and corresponding area under ROC curve for the test sets are 93.8% [92.3, 95.3], 92.2% [90.0, 94.3], and 98.4% [97.8, 99.0], respectively. Inter-site analysis: training using LA data and testing on Utah data resulted in corresponding results of 94.2% [92.0, 96.5], 81.5% [76.2, 86.7], 97.6% [96.5, 98.7], respectively. Utah training and LA testing produced 95.1% [93.3, 96.9], 91.9%, [88.9, 94.9], 98.9% [98.5, 99.4].
conclusionsTouchless monitoring can provide the basis for quantitative, continuous monitoring of neonatal activity. IMPACT: We investigated the feasibility of non-contact ('touchless') monitoring of neonatal activity based on depth sensing technology. Touchless monitoring offers a sensor and wire-free solution for monitoring activity. The findings support the need for further investigation of the method to determine associations with the measured activity and clinical outcomes.
