Central auditory testing in young Tanzanian children: feasibility and relationship to cognition.
Article in International journal of audiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveCentral auditory tests (CATs) typically target children aged six and older and are not included in paediatric cognitive assessment. CATs have shown significant correlations with neurocognitive processing ability in adults. Whether children under six can reliably complete CATs or if CAT performance correlates with cognitive ability in children with normal hearing is unclear. This study aimed to determine the feasibility of conducting CATs in young children and investigate whether performance on CATs could predict neurocognitive function in a cohort of young Tanzanian children. If young children can complete CATs and their results correlate with neurocognitive function, CATs could supplement cognitive screening in young children.
designData are from the first visit of an ongoing longitudinal study in Dar es Salaam, Tanzania. Each child was administered four CATs (the Hearing in Noise Test-HINT, Triple Digit Test-TDT, Staggered Spondaic Words test-SSW, and Gap Detection test-Gap) and one non-verbal cognitive test (Leiter-3). Performance on the CAT battery (HINT, TDT, SSW) was compared to performance on the Leiter-3, a non-verbal neurocognitive assessment. STUDY SAMPLE: Cross-sectional study in an infectious disease centre in Dar es Salaam, Tanzania. Participants included 486 Tanzanian children (50.6% female) aged 3-9 years with 46.7% living with HIV.
resultsOver 70% of children completed at least one CAT during their first visit (average age 6.29 years) with 61% able to complete three (HINT, TDT, and SSW), minus Gap. By age five, 62.5% of children could complete the CAT battery. Completing the CAT battery predicted higher IQ, and performance on the battery was associated with stronger cognitive abilities.
conclusionsThe studied CAT battery, minus Gap detection, could be completed reliably by age five. CATs and cognitive domains (IQ, processing speed, memory) were significantly associated. Administering CATs is feasible in children younger than six, potentially providing a valuable supplementary tool to assess auditory and cognitive function.
