TABLE 2.

Incidence of Main and Secondary Outcomes in 5,017 Children Who Survived PICU Admission Before Their Fifth Birthday

Outcome	PICU Sample	Matched Controls	Difference
Main outcome
% below NMS on both numeracy and reading	14.03	8.96	5.07% (z = 7.96)a
Secondary outcomes
% below NMS on numeracy or reading	24.64	17.38	7.25% (z = 8.92)a
% below NMS on all NAPLAN domains	11.94	7.32	4.62% (z = 7.83)a
% below NMS on at least one NAPLAN domain	31.81	24.41	7.40% (z = 8.25)a

NAPLAN = National Assessment Program—Literacy and Numeracy, NMS = National Minimal Standard.

^ap < 0.001,

The proportions of students failing to meet NMS (defined as a score below 270 or being exempt from testing) during the NAPLAN are
compared between PICU survivors and matched controls. Data are based on pooled results of NAPLAN testing between 2008 and 2017. Z-statistics from proportions test are shown.
Italics indicate significance (p < 0.001).
