  Figure 2.. Respiratory stability index (RSI) vs. mean peripheral capillary oxygen saturation (SpO2) in patients (A) with oxygen inhalation after admission (r=0.17, P=0.60; red solid line A+, regression line); and (B) without oxygen inhalation after admission (red open circles; r=0.37, P=0.06; red dash line A−, regression line ) and before discharge (blue open triangles; r=0.05, P=0.76; blue dash line B−, regression line).

  Figure 3.. Respiratory stability index (RSI) vs. 3% oxygen desaturation index (3%ODI) after admission (red circles; r=−0.63, P<0.01; red solid line A, regression line) and before discharge (blue triangles; r=−0.45, P<0.01; blue solid line B, regression line).

• 

  Figure 4.. Respiratory stability index (RSI) vs. respiratory disturbance index (RDI) after admission (red circles; r=−0.56, P<0.01; red solid line A, regression line) and before discharge (blue triangles; r=−0.45, P<0.01; blue solid line B, regression line).
