Serial evaluation of the change in the daily PELOD-2 score from day 1, adjusted for baseline value (PELOD-2 score on day 1)

Variable	Odds ratio	95 % CI	p value
PELOD-2 score on day 1	1.30	1.22–1.39	<0.0001
Change in PELOD-2 score
Day 1–day 2	1.33	1.21–1.47	<0.0001
Day 1–day 5	1.26	1.15–1.39	<0.0001
Day 1–day 8	1.28	1.15–1.43	<0.0001
Day 1–day 12	1.38	1.20–1.58	<0.0001

Odds ratio (OR) for death is provided with a 95 % CI. The cumulative OR of death can be calculated as follows: (OR of PELOD-2 score on day 1)^{PELOD-2 score on day 1} × (OR of change in score from day 1 to specific day)^{PELOD-2 score on specific day – PELOD-2 score on day 1}. For example, for a child whose score is 10 on day 1 and 6 on day 12 (change in score −4), the OR for death would be 1.30¹⁰ × 1.38⁻⁴ = 3.80
