Normative Values for Auditory Brainstem Responses and Wave V Thresholds in Indian Neonates and Infants.
Article in Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Click-evoked auditory-brainstem-response (ABR) is widely used for hearing screening in neonates and infants. However, their normative values are based on small studies. This retrospective study was done at a tertiary-care centre where click-ABR based screening is done in all newborns. ABR records (Nihon-Kohden machine, model MEB-9400K) of 420 healthy neonates (preterm 75; full-term 32) and infants (113) done over a period 4 years (2014-2018) were analysed retrospectively. Sick neonates and those with Wave V threshold > 40 dbnHL were excluded. Infants were divided into four groups based on post-conceptual age, Group A (75): 34-36 weeks; Group B (44): 37-40weeks; Group C (188):41 weeks-1 month; and Group D (113): 1-6months. The mean absolute latencies for wave I, wave III, and wave V varied from 1.45-1.56 milliseconds (ms), 4.14-4.37 ms, and 6.36-6.81 ms respectively. Interpeak latencies for I-V and I-III varied from 4.91 ms to 5.22 ms and 2.69 ms to 2.81 ms respectively. Older infants had lower absolute and interpeak latencies. Late preterm babies were not different from term babies suggesting early maturation of brainstem pathways.
