Effects of Preoperative Breathing Exercise on Postoperative Outcomes for Patients With Lung Cancer Undergoing Curative Intent Lung Resection: A Meta-analysis.

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
objectiveTo determine the benefits of preoperative breathing exercises on hospital length of stay (LOS), pneumonia, postoperative pulmonary complications (PPC), 6-minute walk distance (6MWD), forced expiratory volume in 1 second (FEV DATA SOURCES: PubMed, EMBASE, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials were comprehensively searched from inception to March 2021. STUDY SELECTION: Only studies including preoperative inspiratory muscle training (IMT) and/or breathing exercises compared with a nontraining control group were included. The meta-analysis was done using Cochrane software for multiple variables including LOS, pneumonia, PPC, 6MWD, FEV DATA EXTRACTION: Two authors extracted the data of the selected studies. The primary outcomes were LOS and PPC. DATA SYNTHESIS: A total of 10 studies were included in this meta-analysis, 8 of which had both IMT and aerobic exercise. Pooled data for patients who performed preoperative breathing exercises, compared with controls, demonstrated a decrease in LOS with a pooled mean difference of -3.44 days (95% confidence interval [CI], -4.14 to -2.75; P<.01). Subgroup analysis also demonstrated that LOS was further reduced when breathing exercises were combined with aerobic exercise (χ
conclusionsPreoperative breathing exercises reduced LOS, PPC, and pneumonia and potentially improved 6MWD in patients undergoing surgical lung cancer resection. Breathing exercises in combination with aerobic exercise yielded greater reductions in LOS. Randomized controlled trials are needed to test the feasibility of introducing a preoperative breathing exercise program in this patient population.
