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
backgroundRecurrence of hiatal hernia after primary repair is a major concern, particularly early recurrence related to technical factors. Reliable preoperative predictors are essential for optimal surgical strategies. Because the hernial sac area can also affect operative complexity, this study aimed to evaluate early recurrence-associated factors and their relationship with operative time using quantitative computed tomography (CT).
methodsWe retrospectively analyzed 48 patients who underwent laparoscopic hiatal hernia repair between July 2012 and July 2025. Preoperative CT was used to measure the maximum diameter and area of the hernial sac in the axial and coronal planes. We examined the association between these parameters and surgical outcomes including recurrence.
resultsEarly recurrence was observed in four patients (8.3%), all of whom required reoperation within 3 days. Patients with early recurrence had longer operative times and larger axial hernial sac areas (p < 0.05). Receiver operating characteristic (ROC) curve analysis demonstrated that the axial maximum diameter provided the highest predictive performance for early recurrence (area under the curve [AUC] = 0.89), with an optimal cutoff value of 117.6 mm. Other parameters, including axial area, coronal area, coronal diameter, and hiatal width, showed moderate predictive ability but none exceeded axial diameter accuracy.
conclusionAxial hernial sac measurements are associated with early recurrence. Preoperative CT-based quantitative assessments may provide valuable information for predicting surgical complexity and recurrence, thereby supporting preoperative risk stratification and surgical planning. Therefore, prospective validation using a larger cohort is warranted.
