Factors Influencing Leaks in Primary Intestinal Anastomoses: An Observational Study.
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 An anastomotic leak (AL) remains a major complication in gastrointestinal surgery, particularly after primary intestinal anastomosis. It contributes to increased morbidity, prolonged hospitalization, and mortality. Objective To identify and evaluate patient, surgical, and perioperative factors associated with the development of anastomotic leaks in individuals undergoing a primary intestinal anastomosis. Methods This observational study was conducted at Sree Balaji Medical College and Hospital, Chennai, and included 70 patients who underwent primary intestinal anastomosis. Data were collected on demographics, comorbidities, surgical details, postoperative outcomes, and complications. Statistical analyses included logistic regression and receiver operating characteristic (ROC) analysis to assess predictive factors. Results The overall incidence of AL was 23.3% (14 out of 70 patients). Higher BMI (p = 0.005), renal disease (p = 0.043; 7 out of 9 patients with renal disease), hypertension (p = 0.041; 5 out of 6 patients), and diabetes (p = 0.029; 5 out of 7 diabetic patients) were significantly associated with AL. Logistic regression showed BMI to be an independent predictor of AL. An ROC analysis indicated predictive utility for BMI and CRP. No significant associations were found with age, gender, smoking, surgical duration, or blood loss. Conclusion BMI and comorbidities such as renal disease, hypertension, and diabetes are key risk factors for AL. Preoperative optimization and risk stratification based on these factors can improve surgical outcomes. Future studies should validate these findings in larger, multicentric populations.
