It is unclear whether these data, usually sampled at a lower frequency, are sufficient for retrospective studies. We investigated what to expect when using one-per-minute data for descriptive statistics. <h4>Methods</h4> One-per-second inspiratory oxygen and saturation were processed to one-per-minute data and compared, on average, standard deviation, target range time, hypoxia, days of supplemental oxygen, and missing signal. <h4>Results</h4> Outcomes calculated from data recordings (one-per-minute = 92, one-per-second = 92) showed very little to no difference. Sub analyses of recordings under 100 and 200 h showed no difference. <h4>Conclusion</h4> In our study, descriptive statistics of one-per-minute data were comparable to one-per-second and could be used for retrospective analyses. Comparable routinely collected one-per-minute data could be used to develop algorithms or find associations, retrospectively.Frontiers in pediatricshttps://www.ebi.ac.uk/biostudies/studies/S-EPMC9133439biostudies-literatureComparing Descriptive Statistics for Retrospective Studies From One-per-Minute and One-per-Second DataPMC9133439Salverda HPauws SDargaville PDekker JWitlox Rte Pas AfalseComparing Descriptive Statistics for Retrospective Studies From One-per-Minute and One-per-Second Data<h4>Background</h4> Large amounts of data are collected in neonatal intensive care units, which could be used for research.
