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

objectivesSpeech intelligibility is reported to be markedly decreased in patients with vestibular schwannoma (VS); however, the relationship between speech intelligibility and hearing level remains poorly characterized.

methodsWe created scatter plots of pure-tone audiometry (PTA) thresholds and speech discrimination scores for 473 patients with sporadic, unilateral VS. Simple regression analysis and Pearson correlation coefficients were calculated and compared with data from 173 patients with asymmetric cochlear hearing loss, including the proportion of patients with unserviceable speech intelligibility.

resultsIn VS patients, speech discrimination score and PTA threshold showed a strong correlation on the affected side, regardless of Koos grade or audiogram shape. The distribution was largely similar to that in asymmetric cochlear hearing loss. Although the proportion of patients with unserviceable speech discrimination was higher for VS than for asymmetric cochlear hearing loss across all hearing levels, the difference was statistically significant only in severe hearing loss.

conclusionWhen adjusted for hearing level, markedly decreased speech discrimination is no longer a characteristic feature of VS.
