Shows results from main analysis and the two sensitivity analyses

Model	30 day mortality odds (95% CI)	1 year mortality odds (95% CI)	Length of stay estimate (95% CI)
Primary analysis:
Mean pain	0.457*** (0.304 to 0.687)	0.710*** (0.571 to 0.881)	−0.916*** (−1.159 to 0.673)
Median pain	0.639*** (0.466 to 0.877)	0.856* (0.727 to 1.008)	−0.696*** (−0.886 to 0.506)
Max pain	0.812*** (0.693 to 0.951)	0.887** (0.790 to 0.995)	0.148* (−0.02 to 0.32)
Categorical pain	0.214*** (0.091 to 0.502)	0.450*** (0.266 to 0.760)	−2.270*** (−2.903 to 1.637)
Sensitivity analysis 1: including all patients regardless of intubation lengths
Mean pain	0.592*** (0.456 to 0.768)	0.898 (0.785 to 1.027)	−0.709*** (−0.866 to 0.552)
Categorical pain	0.328*** (0.184 to 0.586)	0.740* (0.527 to 1.037)	−1.706*** (−2.110 to 1.302)
Sensitivity analysis 2: excluding hospital mortality patients
Mean pain	0.803 (0.567 to 1.137)	1.027 (0.889 to 1.187)	−0.701*** (−0.858 to 0.544)
Categorical pain	0.709 (0.309 to 1.625)	1.038 (0.714 to 1.509)	−1.680*** (−2.082 to 1.278)

*, **, *** denotes significance at the 90%, 95% and 99% level, respectively.
