Extrasystoles on 24-h Holter Monitoring During the First Year of Life.

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
aimTo assess the natural course of extrasystoles and their association with tachyarrhythmias on 24-h Holter monitoring during the first year of life.
methodsA retrospective chart review was performed among newborns referred for 24-h Holter monitoring at Tampere University Hospital from 2011 to 2017. Children with more than 1% extrasystoles on the initial Holter recording were included.
resultsIn total, 75 children and 290 Holter recordings were included. Forty-seven (63%) children were followed up due to atrial premature contractions (APCs) and 28 (37%) children were followed up due to ventricular premature contractions (VPCs). The amount of extrasystoles peaked during the first 14 days and decreased significantly during the first 2 months. However, in one-third of the children, extrasystoles increased between recordings. Extrasystoles disappeared during the first year among 92% of children with APCs and 78% of children with VPCs. Short supraventricular or ventricular tachycardias were found in 17 (23%) children's recordings. A higher percentage of extrasystoles was associated with tachyarrhythmias.
conclusionThe results support the prevailing understanding regarding the favourable prognosis of extrasystoles in newborns. Serial Holter monitoring may be advisable during the newborn period for infants with frequent extrasystoles, as some may be susceptible to tachyarrhythmias.
