Intermittent Hypoxemia and Neurodevelopmental Impairment at 12 and 24 Months in Preterm Infants.

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
introductionNeonatal studies have shown a relationship between intermittent hypoxemia (IH) and long-term sequelae although definitions of IH have varied. Employing multiple thresholds of IH and a wider gestational aged cohort of preterm infants, we hypothesized that increased IH exposure during the first month of life was associated with neurodevelopmental impairment (NDI) at 12 and 24 months corrected age.
methodsIH (<80% or <90%) were documented from day of life 8 to 28 (n = 175 infants <31 weeks gestation). Referral for NDI was identified (Ages and Stages Questionnaire, ASQ-3) at 12- and 24-month corrected age (>2 SD below the mean for gross motor, communication, fine motor, problem solving, and/or personal-social skills).
resultsUnadjusted models revealed a significant association between increased IH and scores in referral range for gross motor, and communication skills (12 months) and gross motor, communication, fine motor, problem solving, and personal-social skills (24 months). In adjusted models, a greater % time <90% and referral scores for communication skills (p = 0.0158) at 12 months remained significant. Subgroup analyses revealed an association between greater % time <80% (12 months, p = 0.0311) and longer IH duration <90% (24 months, p = 0.0374) and scores in referral range for any domain in infants ≥29 weeks gestation.
conclusionThere was a limited relationship between IH and ASQ-3 scores in referral range for NDI with an association between IH and ASQ-3 referral at 12 and 24 months in infants ≥29 weeks gestation suggesting IH may be a risk factor for NDI in older infants with less competing morbidities.
