ALT Box and Whisker plots comparing (A) mean saturations, (B) mean nadir SpO2>3%, (C) ODI3, (D) ODI4, and (E) ODI10 across weeks and between groups. ‘Boxes’ show the 25th centile and 75th centile for each measure, and ‘Whisker(s)’ show no more than 1.5 times the IQR from the box edges with outliers indicated by an ‘x’. GA, gestational age; MLPT, moderate-late preterm; ODI, Oxygen Desaturation Index; SpO2, mean peripheral oxygen saturation.

ALT Physical measurements of neonatal video laryngoscope blades (size 0). Shown are C-MAC, GlideScope, InfantView and NeoView and a conventional Miller blade. All blades assessed were straight, Miller-type neonatal blades. Measurements included: (A) working blade length measured from the mounting point; (B) blade angle (degrees); (C) distance from camera to distal blade tip; (D) full blade length and (E) blade width. All measurements were recorded in millimetres unless otherwise stated.
