Risk factors for postoperative respiratory complications following retroperitoneal laparoscopic adrenalectomy: a cohort study.
Article in Gland surgery, 2025. 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
Background: Retroperitoneal laparoscopic adrenalectomy (RLA) is a minimally invasive technique known for its benefits, including reduced pain and quicker recovery. Despite these advantages, respiratory complications remain a notable concern, highlighting the importance of identifying risk factors to enhance perioperative care. This study aimed to explore the determinants of respiratory complications following RLA. Methods: A retrospective analysis was conducted on the clinical data of 569 patients who underwent RLA for adrenal lesions in the Department of Urology at Beijing Anzhen Hospital from January 2012 to December 2021. The data collected included age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) score, operative time, estimated intraoperative blood loss, tumor laterality, type of resection, lesion size, preoperative comorbidities and postoperative complications. Univariate and multivariate logistic regression models were used to identify risk factors for respiratory complications following RLA. The area under the receiver operating characteristic (ROC) curve with area under the curve (AUC) was calculated to evaluate the predictive value of relevant factors for respiratory complications. Results: A total of 30 patients (5.27%) developed postoperative respiratory complications following RLA, including 16 cases of respiratory infection (2.8%), 9 cases of postoperative cough requiring antitussive medication (1.6%), 3 cases of bronchial asthma (0.5%), and 2 cases of respiratory failure (0.4%). Univariate logistic regression analysis identified prolonged operative time [odds ratio (OR) =1.007, P=0.043], preoperative respiratory disease comorbidity (OR =6.005, P<0.001), and right-sided RLA (OR =3.544, P=0.002) as associated with an increased risk of postoperative respiratory complications. Multivariate logistic regression analysis showed that preoperative respiratory disease comorbidity (OR =7.243, P<0.001) and right-sided RLA (OR =4.227, P=0.001) were independent risk factors for postoperative respiratory complications. The AUC for the predictive model, which included operative time, preoperative respiratory diseases, and right-sided RLA, was 0.752 (95% CI: 0.657-0.848). Conclusions: Respiratory complications following RLA are associated with factors such as operative time, preoperative respiratory disease comorbidity, and right-sided RLA. Identifying these risk factors preoperatively may help optimize surgical planning and reduce the incidence of postoperative complications.
