Subgroup analysis

Data unclear:

• Multiple/range of values given for tidal volume
• No PEEP values greater than zero (dichotomisation is at zero)
• Li et al. results are split in two in the primary outcome, but not clear if tidal volume etc. are the same in both sets of results.

Tidal volume (>6 vs <=6mL/kg)

PEEP (<0 vs 0)

Anesthesia type (TIVA vs inhaled)
