Dummy/pacifier use in preterm infants increases blood pressure and improves heart rate control.
Article in Pediatric research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundPreterm infants are at increased risk of sudden infant death syndrome (SIDS). Use of a dummy/pacifier is thought to be protective against SIDS; accordingly, we assessed the effects of dummy/pacifier use on blood pressure, cerebral oxygenation, and heart rate control over the first 6 mo of life after term corrected age (CA) when SIDS risk is greatest.
methodsThirty-five preterm infants were studied longitudinally at 2-4 wk, 2-3 mo, and 5-6 mo CA. Cardiac control was assessed from spectral indices of heart rate variability (HRV) in the low frequency (LF) and the high frequency (HF) range, and the ratio of HF/LF indicating sympathovagal balance was calculated.
resultsOverall, at 2-3 mo, mean arterial pressure was significantly higher in the supine position in dummy/pacifier users in both quiet sleep (70 ± 2 vs. 60 ± 2 mm Hg; P < 0.05) and active sleep (74 ± 3 vs. 69 ± 2 mm Hg; P < 0.05). Dummy/pacifier users had higher LF HRV and LF/HF ratio and lower HF HRV.
conclusionDummy/pacifier use increased blood pressure during sleep, at the age of greatest SIDS risk. Overall, LF HRV was elevated and HF HRV reduced in dummy/pacifier users, suggesting that dummy use alters cardiac control in preterm infants.
