Role of Newborn Hearing Screening Done Over One Year in a Tertiary Care Hospital: A Cross-Sectional Study.
Article in Cureus, 2024. 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
backgroundNewborn hearing screening (NHS) is universally acknowledged as a critical early intervention to prevent adverse developmental outcomes caused by undetected hearing loss. Despite its proven benefits, the implementation of NHS varies, especially in tertiary care hospitals that manage high-risk neonates. This study investigates the effectiveness and implementation of NHS protocols in these settings. METHODOLOGY: This cross-sectional study was conducted in the Department of Neonatology at Saveetha Medical College, Chennai. All newborns delivered between January 2023 and December 2023 were included. Screening involved initial otoacoustic emissions (OAEs) tests, automated auditory brainstem response (AABR) followed by brainstem evoked response audiometry (BERA) for those who failed. Data on demographic characteristics, screening results, and follow-up compliance were collected and analyzed.
resultsA total of 1,398 neonates were screened. Initial screening resulted in 416 (29.7%) referrals. Follow-up screenings showed high compliance rates, with significant detections of hearing impairments through BERA. The screening was completed for 1,341 babies. Fifty-five babies were lost to follow-up. Of these, 2 babies (0.1%) with a high risk for hearing loss were diagnosed with bilateral severe hearing loss. The study also noted demographic factors such as kinship and obstetric history that might influence hearing loss risks.
conclusionsNHS plays a vital role in the early detection and management of hearing impairments, which is crucial for preventing negative impacts on a child's development. This study advocates for the systematic implementation of NHS protocols in all tertiary care hospitals, especially those serving high-risk neonates, to ensure optimal developmental outcomes.
