Flexible Laryngoscopy Findings in Patients Undergoing Thyroidectomy in North-Central Nigeria.
Article in Journal of the West African College of Surgeons. 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: Thyroidectomy is one of the most commonly performed surgical procedures in Africa and indeed globally. Although the prevalence of vocal cord paralysis (VCP) and incidental laryngopharyngeal pathologies (LPPs) is reported to be low, the rate of occurrence is not known in our environment. Therefore, preoperative laryngeal examination provides not only a more accurate assessment of operative risks but also additional information that may help avoid legal problems with undetected preoperative voice disorders. Aim: To evaluate the flexible laryngoscopy findings and determine the prevalence of VCP and incidental LPPs in patients undergoing thyroidectomy. Materials and Methods: A cross-sectional study among patients with goitre who were being planned for thyroidectomy using an interviewer-administered structured questionnaire. Ethical clearance and informed consent were obtained. Flexible laryngoscopy was performed, and data was analyzed using the Statistical Product and Service Solutions version 28.0. Results: Eighty-two patients were evaluated. Preoperative flexible laryngoscopy showed VCP in 4 (4.9%) patients, incidental LPPs in 7 (8.5%), and both conditions in 1 (1.2%). Laryngopharyngeal reflux disease (LPRD) was found in most (three of the eight patients). Other incidental LPPs were right vocal cord nodule in 2 (2/8), bilateral vocal cord nodule in 1 (1/8), right arytenoid mass in 1 (1/8), and left arytenoid subluxation in 1 (1/8). Conclusion: This study showed VCP's prevalence to be 6.1% and 9.8% for incidental LPPs in patients with goitre undergoing thyroidectomy. LPRD was the most commonly identified pathology.
