Table 4. Comparisons for vitals and blood gases. This is a summary of the results in Fig. 4.

Row		RR	HR	SpO2	DBP	SBP	Temp	pO2	pH	pCO2	Hcrit	Blood Bicarb	Serum Bicarb	K+	Na+
1	Group A vs. B at admission	↑↑↑		↓↓↓			↓	↑↑↑	↓↓↓			↓	↓↓↓
2	Group C vs. D at admission	↑↑↑		↓↓↓		↓↓↓	↑↑↑						↓↓↓		↓↓
3	Group C vs. D at upgrade	↑↑↑	↑↑↑	↓↓↓			↑↑↑		↓	↑	↑				↓↓
4	at admission vs. at upgrade for C	↓↓↓	↓↓↓	↑↑↑	↓↓↓	↓↓↓	↓↓↓				↓↓↓		↓↓↓		↑↑↑
5	at admission vs. at upgrade for D		↓↓↓	↑↑↑			↓↓↓				↓↓↓		↓		↑↑↑
6	C improved or unchanged but D deteriorated

Note:

Note that at upgrade means 1 day prior to upgrade, ↑ = significant increase where p < 0.05, ↑↑ = significant increase where p < 0.01, ↑↑↑ = significant increase where p < 0.005. ↓ = significant decrease where p < 0.05, ↓↓ = significant decrease where p < 0.01, ↓↓↓ = significant decrease where p < 0.005. X: denotes variables that showed C improved or plateaued, but D deteriorated between two time points.
