An evidence-based systematic review of frequency lowering in hearing aids for school-age children with hearing loss.
Synthesis in American journal of audiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
purposeWe developed 1 clinical question for this review, which addressed the comparison of hearing aids using frequency lowering compared to conventional processing amplification for outcomes of audibility, speech recognition, speech and language, and self- or parent-report for children with hearing loss.
methodWe systematically searched 26 databases for studies addressing a clinical question and meeting all inclusion criteria. We evaluated studies for methodological quality and reported or calculated effect sizes when possible.
resultsThe literature search resulted in the inclusion of 5 studies. We implemented several different frequency-lowering strategies across studies; 2 studies used nonlinear frequency compression, 2 used frequency transposition, and 1 used frequency compression with dynamic consonant boost.
conclusionsWhereas methodological limitations of the included studies preclude the formulation of strong conclusions, findings were generally positive across frequency-lowering strategies and outcomes. Additional high-quality research is needed in this area.
