Table 2.

Respiratory rate classification over time (measured by expert counter)

	Time points
	Baseline → 1 minute, N = 163	1 minute → 3 minutes, N = 157	3 minutes → 5 minutes, N = 153	Baseline → 3 minutes, N = 158	Baseline → 5 minutes, N = 154
Classification at time points	% (95% CI) [N]	% (95% CI) [N]	% (95% CI) [N]	% (95% CI) [N]	% (95% CI) [N]
Normal–normal	70.6 (62.9–77.4) [115]	70.1 (62.3–77.1) [110]	72.5 (64.8–79.4) [111]	70.6 (63.8–78.4) [113]	72.1 (64.3–79.0) [111]
Normal–Fast	4.9 (2.1–9.4) [8]	0.6 (0.0–3.5) [1]	0.7 (0.0–3.6) [1]	3.8 (1.4–8.1) [6]	3.9 (1.4–8.3) [6]
Fast–normal	0.0 (0.0–2.2) [0]	2.5 (0.7–6.4) [4]	0.7 (0.0–3.6) [1]	1.3 (0.2–4.5) [2]	1.3 (0.2–4.6) [2]
Fast–fast	24.5 (18.1–31.9) [40]	26.8 (20.0–34.4) [42]	26.1 (19.4–33.9) [40]	23.4 (17.1–30.8) [37]	22.7 (16.4–30.2) [35]

The difference in total number of RR counts between Table 2 and Figure 2 is due to the fact that the expert counter lost count of the RR at two separate instances, once at the 1-minute time point and once at the 3-minute time point. However, this did not lead to the exclusion of all of the child´s measurements; hence, because Table 2 accounts for the classification change between two time points, these instances lead to one lesser observation for the change between the 1–3 and 3–5 time points, respectively.
