Figure. Risk-Adjusted Probabilities of Components of Neurodevelopmental Impairment and Bayley Scales of Infant Development, by Tracheostomy.

Figure

Error bars represent 95% confidence intervals for risk-adjusted probabilities. Probabilities were adjusted for center, time period, birth weight, sex, antenatal steroid exposure, race, presence of syndromes or major malformations, brain injury, sepsis, NEC, severe ROP, surgical ligation of PDA, BPD (oxygen dependence at 36 weeks) and prolonged ventilation. Language delay is defined as <85 (ie, >1 standard deviation below the expected mean score of 100, on the language scale of the Bayley Scales of Infant Development-III). Neurologic delay is defined as moderate to severe cerebral palsy with GMFCS level of 2 or higher.
