Pre- and Post-operative Speech Audiometry Evaluation in Patients with Chronic Otitis Media.
Article in The journal of international advanced otology, 2020. 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
objectivesThe primary function of the human auditory system is to ensure proper speech comprehension. Speech audiometry enables the assessment of the conductive and the sensory aspects of the ears, providing some insight into the central auditory processing function. MATERIALS AND
methodsWe conducted an analysis of 79 patients with chronic otitis media (COM) undergoing surgery at the Department of Otolaryngology, Jagiellonian University Medical College, in Kraków between 2005 and 2014. Tonal audiometry and speech audiometry were used as part of the hearing assessment. The pre-operative and long-term post-operative findings were compared, focusing mainly on speech audiometry.
resultsAt the end of the mean 10-year follow-up, a significant percentage worsening in speech comprehension from the baseline was demonstrated in group III (hearing loss > 70 dB(decibels)), as compared with the remaining groups. There was a significant (p = 0.017) difference in speech comprehension between the treated and contralateral ears, with the mean maximum speech comprehension rates of 80% in the treated ear versus 92% in the contralateral ear.
conclusionWe demonstrated a correlation between the findings of tonal audiometry and speech audiometry. The severe damage caused by chronic middle ear diseases not only leads to conductive hearing loss but also acts as a significant contributor to poor speech comprehension in a long-term follow-up. The speech comprehension in a healthy ear is significantly better than in a diseased ear. Middle ear reconstructive surgery offers the maximum improvement in speech comprehension at the hearing loss of 41 to 70 dB in speech audiometry.
