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

backgroundHearing loss is highly prevalent among adults and is a major contributor to communication difficulties, particularly in older populations. Pure-tone audiometry (PTA) is routinely used to assess hearing sensitivity; however, threshold measurements alone may not fully reflect functional speech understanding. This study aimed to evaluate speech discrimination performance in a primary care otolaryngology population and to identify baseline factors associated with poor speech discrimination.

methodsThis retrospective observational study included patients who underwent PTA and word recognition score (WRS) testing at a primary care otolaryngology clinic between September 1, 2025, and January 20, 2026. Hearing levels were classified according to the World Health Organization (WHO) grading system based on better ear PTA. Poor speech discrimination was defined as better-ear WRS < 70%. Multivariable logistic regression analysis was performed to identify factors associated with poor speech discrimination.

resultsA total of 503 patients were included, with a median age of 50 years (interquartile range [IQR], 35-63), and 43.7% were male. Twenty patients were excluded from hearing grade analyses due to invalid audiometric results. Poor speech discrimination was observed in 43 patients (8.9%). In multivariable analysis, higher better ear PTA (odds ratio [OR], 1.12 per 1-dB increase; 95% confidence interval [CI], 1.07-1.17; p < 0.001) and older age (OR, 1.09 per 1-year increase; 95% CI, 1.03-1.15; p = 0.003) were independently associated with poor speech discrimination. Sex, noise exposure, and systemic comorbidities were not significantly associated with speech discrimination outcomes. Sensitivity analyses using alternative WRS thresholds yielded consistent results.

conclusionsIn a primary care otolaryngology population, poor speech discrimination is primarily associated with hearing threshold severity and age. Routine assessment of speech discrimination in addition to PTA may improve identification of patients at risk for functional communication impairment and facilitate earlier intervention.
