Figure 2.. From: Tidal Volume Reduction in Patients with Acute Lung Injury When Plateau Pressures Are Not High.

Mortality difference by quartile of Day 1 Pplat. The range of Pplat levels in cm H2O and the number of patients (n) is detailed in each bar of the graph. ARR = absolute risk reduction; CI = confidence interval.

Figure 1.. From: Tidal Volume Reduction in Patients with Acute Lung Injury When Plateau Pressures Are Not High.

Robust locally weighted regression and smoothing (Lowess) plot (bandwidth, 0.4) of mortality and Day 1 plateau pressure (Pplat; cm H2O) among patients enrolled in the ARDS Network study (n = 787) (4, 47). The Lowess method is a nonparametric smoother that uses overlapping neighborhoods of data to estimate a local effect. A bandwidth of 0.4 means 20% of the data on either side of a given Pplat will contribute to a local estimate of mortality at that Pplat. Data at the high and low ends of the curve therefore represent fewer observations. Data are smoothed using a tricubic weight function so that points furthest from the Pplat of interest are assigned the least weight (and approach zero).
