A prospective randomized crossover trial studying the effects of maternal heartbeat and voice sounds on resting energy expenditure in preterm infants.
Trial report in Journal of perinatology : official journal of the California Perinatal Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo compare resting energy expenditure (REE) among premature infants exposed to recorded maternal heartbeat and voice (MHV) vs. ambient noise. STUDY
designA prospective, randomized crossover pilot trial evaluating the effect of MHV on REE using indirect calorimetry in hemodynamically stable premature infants born at 26-34 weeks' gestation. MHV recordings were digitally overlapped, and exposure sequence was randomized.
resultAmong 34 measurements from seventeen subjects, REE was significantly lower during MHV exposure compared to ambient noise (61.4 ± 10.3 vs. 70.9 ± 10.3 kcal/kg/day, p = 0.0001). Mean heart rate was also significantly lower with MHV (144 ± 13 vs. 150 ± 11 bpm, p = 0.028), with no differences in other vital signs.
conclusionREE of premature infants decreased during exposure to MHV when compared with ambient noise. MHV may serve as a potential noninvasive therapeutic intervention to improve metabolic efficiency in premature infants, potentially helping with improved growth.
