The Impact of Fissure-Adjacent Localization on Rupture Risk in Pulmonary Hydatid Disease.
Article in Cureus, 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 Pulmonary hydatid cyst (PHC) rupture is a serious complication that can increase surgical difficulty and postoperative morbidity. Identifying preoperative predictors of rupture is essential for patient risk stratification and optimal surgical timing. This study aimed to evaluate clinical, radiological, and laboratory factors associated with cyst rupture, with a particular focus on the anatomical relationship with lung fissures. Methods A retrospective analysis was conducted on 37 patients who underwent surgery for pulmonary hydatid cysts between January 2012 and December 2021. Patients were categorized into ruptured and intact cyst groups. Demographic, radiological, hematological, and operative data were compared. Logistic regression was used to identify independent predictors of rupture. Results Cyst rupture was observed in 19 patients (51.4%). Preoperative C-reactive protein (CRP) levels and the presence of fissure connection were significantly higher in the ruptured group (p < 0.05). Multivariate logistic regression revealed that fissure relationship was an independent predictor of rupture (odds ratio {OR}: 5.150; 95% confidence interval {CI}: 0.957-27.719; p = 0.049). Cyst size and location were not significant predictors in the adjusted model. The model showed acceptable fit (Hosmer-Lemeshow p = 0.094) and moderate predictive power (Nagelkerke R² = 0.447). Conclusion Fissure involvement is a key anatomical risk factor for pulmonary hydatid cyst rupture and should be carefully assessed during preoperative imaging. The early identification of fissure-associated cysts may guide surgical planning, reduce complications, and improve patient outcomes.
