Fig 1 Flowchart of trial design, inclusion, and exclusion. *Exclusions from the control group: extensive pleural adhesions, converted to transhiatal procedure (n=1); insufficient collapse of the right lung, converted to transhiatal procedure (n=2); irresectable tumour (n=1); gastrectomy instead of oesophagectomy (n=1). †Exclusions from the CPAP group: irresolvable hardware issues with robotic system, converted to transhiatal procedure (n=2); extensive pleural adhesions, converted to transhiatal procedure (n=1); irresectable tumour (n=2).

Fig 3 Concentration changes of cytokines in BALF. Longitudinal concentrations of cytokines (a, IL-1α; b, IL-1β; c, IL-6; d, IL-10; and e, TNFα) as change from baseline (preoperative) in the left and right lung of patients with and without CPAP. Data represent the mean (sem) difference of the natural logarithm concentration (Ln) from t1. P-values indicate the difference between the control and CPAP groups at t4. Sample moments: t1, preoperative; t2, 2 h after collapse; t3, 2 h after reinsufflation; t4, postoperative.

Fig 4 Concentration changes of chemokines in BALF. Longitudinal concentrations of chemokines (a, MCP-1; b, MIP-1α; c, PARC; and d, IL-8) as change from baseline (preoperative) in the left and right lung of patients with and without CPAP. Data represent the mean (sem) difference of the natural logarithm (Ln) concentration from t1. P-values indicate the difference between the control and CPAP groups at t4. Sample moments: t1, preoperative; t2, 2 h after collapse; t3, 2 h after reinsufflation; t4, postoperative.
