1 · What the graph read from it

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.

2 · The registry

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

<p>Introduction: Type 2 diabetes mellitus (T2DM) is associated with multiple systemic complications, including vascular and neuropathic changes that can affect the auditory pathway. These alterations may contribute to hearing loss and difficulty in speech perception, particularly in noisy environments. This study aimed to evaluate speech recognition in noise among patients with T2DM using the Signal-to-Noise Ratio 50 (SNR-50) and to examine its relationship with disease duration and glycemic control.

methodsAn analytical cross-sectional study was conducted at a tertiary care hospital. Ninety subjects aged 30-60 years were recruited, comprising 45 patients with T2DM and 45 age-matched nondiabetic controls. All participants underwent audiological evaluation including pure-tone average (PTA), tympanometry, speech reception threshold (SRT), speech identification score (SIS), uncomfortable loudness level (UCL), and SNR-50 testing. Data were analyzed to assess differences between groups and correlations with diabetes duration and glycemic control (HbA1c levels).

resultsPTA values were higher in patients with T2DM compared to controls, indicating worse peripheral hearing. Diabetic patients demonstrated poorer speech perception, confirmed by elevated SRT values. SNR-50 values were significantly impaired in T2DM patients relative to controls. Longer duration of diabetes (>10 years) was associated with reduced SIS and higher PTA and SRT values compared to patients with 5-10 years of disease. A statistically significant positive correlation was observed between SNR-50 and duration of diabetes. While PTA, SRT, and SIS did not show significant variation across HbA1c categories, SNR-50 values worsened significantly with poorer glycemic control.

conclusionT2DM is associated with impaired speech perception and poorer hearing outcomes, with disease duration exerting a cumulative adverse effect. SNR-50 performance was significantly related to glycemic control, suggesting that subtle central auditory dysfunction may coexist with or precede peripheral hearing loss in diabetic patients. Early evaluation of auditory function in T2DM may aid in timely identification and management of communication difficulties. </p>.
