Relation Between Glycated Hemoglobin Level and Hearing Loss in Type 2 Diabetic Patients.

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: Glycemic control and the efficacy of therapy in diabetic patients with type 2 diabetes during the previous 2-3 months are usually evaluated by measuring the glycated hemoglobin (HbA1c). Our aim is to study the correlation between serum glycated hemoglobin level (HbA1c) and the hearing thresholds in diabetic patients. Methods: A case-control study was conducted in the Audio-Vestibular Medicine Unit, xxxx University on 82 subjects. The subjects were divided into 2 groups: the first group consisted of 42 diabetic patients and the second group consisted of 40 healthy subjects. All the participants underwent a pure tone audiogram and speech audiometric evaluation. All participants also underwent diabetes laboratory assessments, including fasting blood glucose serum level and serum HbA1c level. The average hearing threshold at frequencies from 250 Hz to 16 000 Hz in both groups was calculated and correlated to different variables. Results: Diabetic patients showed higher hearing thresholds than those of the control group, with an increasing tendency of elevation of the hearing threshold levels toward the higher frequencies in both groups. There was no statistically significant difference in the hearing thresholds between patients with diabetes < 5 years (20 subjects) and those with a duration of ≤ 5 years (22 subjects). Also, there was no statistically significant difference in the average hearing thresholds among type 2 diabetic patients based on fasting blood sugar level results, except at 16 000 Hz. Conclusion: Poor glycemic control status [Hb A1c ≥ 7%] is significantly associated with elevated hearing thresholds.
