FIGURE 6.

Relationship between diaphragm fatigability outcomes and IPTL. Scatter plot showing the relationship between D‐VA after IPTL and TTF (a), P_DI,TW and TTF (b), D‐VA after IPTL and cumulative diaphragm pressure output (c), and P_DI,TW after IPTL and cumulative diaphragm pressure output (d). Dashed line is a linear regression representing the relationship between the associated variables. D‐VA, diaphragm voluntary activation; IPTL, inspiratory pressure threshold loading; P_DI,TW, transdiaphragmatic twitch amplitude
