Effect of intraoperative ventilation strategy on postoperative pulmonary complications in thoracic surgery under general anesthesia: a meta-analysis.
Synthesis in Journal of cardiothoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThoracic surgery is essential for treating various chest diseases. The ventilation strategies used during surgery can affect the risk of postoperative pulmonary complications (PPCs).
objectiveThis meta-analysis assesses how lung-protective ventilation strategies (LPVS) affect PPCs compared with conventional strategies in adult patients undergoing thoracic surgery under general anesthesia through a meta-analysis.
methodsA systematic literature search was conducted across PubMed, Embase, Cochrane, and Web of Science databases. Heterogeneity among studies was analyzed using the Q test and I² statistic Pooled results were presented as relative risk (RR) with 95% confidence intervals (CIs).
resultsA total of 11 randomized controlled trials, encompassing 1915 participants, were analyzed. LPVS significantly reduced the incidence of PPCs (RR = 0.82, 95%CI = 0.71–0.95). Subgroup analyses revealed significant effects in Asian countries (RR = 0.59, 95%CI = 0.39–0.87) and patients ≥ 60 years old both in control (RR = 0.84, 95% CI = 0.72–0.98) and research group (RR = 0.82, 95% CI = 0.70–0.9). Significant effects were also found in control group with tidal volume ≥ 8 ml/kg (RR = 0.67, 95% CI = 0.51–0.89) and research group with tidal volume ≤ 5 ml/kg (RR = 0.84, 95% CI = 0.73–0.98).
conclusionLPVS effectively reduce PPCs in thoracic surgery, particularly among older patients. Future research should standardize protocols and explore long-term outcomes.
