Risk of Malignancy in Long-Standing Goiters: A Retrospective Study at Khartoum Teaching Hospital, Sudan.
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
backgroundGoiter is a common condition in Sudan, often presenting with a wide range of clinical features. While the risk of malignancy in long-standing goiters is generally considered low, it remains a clinical concern, especially with a prolonged disease duration. Surgical intervention should be considered in managing goiters of prolonged duration to mitigate this risk.
aimsThis study aims to evaluate the risk of malignancy and identify the subtypes of malignant transformation in patients with long-standing goiters undergoing thyroidectomy at Khartoum Teaching Hospital, Sudan.
methodsThis retrospective descriptive study was conducted at Khartoum Teaching Hospital, a major tertiary care center in Sudan, over 18 months from March 2017 to September 2018. A total of 160 patients aged 18 years and above with long-standing goiters scheduled for thyroidectomy were included. Data were collected from patient medical records, capturing demographic information, clinical characteristics, and histopathological findings, and compiled directly into a spreadsheet. Preoperative, intraoperative, and postoperative assessments included clinical examinations and thyroid function tests. Histopathological analysis of thyroid specimens determined the presence and type of malignancy. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States), with chi-square (χ²) tests applied to assess associations, and a p-value of <0.05 was considered statistically significant.
resultsThe mean age of participants was 52.5 ± 14 years, with a male-to-female ratio of 1:4.5. Pressure symptoms were reported in 151 patients (94.4%), and 11 patients suffered from recurrent laryngeal nerve injury and five patients were found to have metastasis at the time of surgery. Histopathological examination revealed malignancy in 54 patients (32.5%), with follicular carcinoma being the most common subtype. Among the malignant cases, 44 were clinically suspected, while 10 (9%) were incidentally discovered. A significant association was observed between clinical diagnosis and histopathological confirmation of malignancy (P = 0.001).
conclusionThis study found a significant rate of malignancy among patients with long-standing goiters undergoing thyroidectomy at Khartoum Teaching Hospital, with follicular carcinoma being the most common subtype. Many cases were incidentally discovered, highlighting the need for thorough preoperative evaluation and patient counseling in regions with endemic goiter.
