Audiological monitoring of patients undergoing multidrug resistant tuberculosis treatment at Jigme Dorji Wangchuk National Referral Hospital and Gidakom Hospital, Bhutan.
Article in Journal of clinical tuberculosis and other mycobacterial diseases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundHearing impairment due to ototoxicity is one common cause adding to global burden of disability. Amikacin and kanamycin are two common Aminoglycosides used to treat multidrug resistant tuberculosis which results in ototoxicity. The mean prevalence rate of multidrug resistant tuberculosis in Bhutan stood at 16%.
objectiveThe study is aimed to establish prevalence rate of hearing impairment due to ototoxicity and secondary side effects which may ascertain specific early intervention.
methodA total of 42 Patients undergoing multidrug resistant tuberculosis treatment participated in the study conducted at Jigme Dorji Wangchuk National Referral Hospital and Gidakom Hospital over a period of one year. Audiological tests were conducted once every month. The severity of ototoxicity was being graded using Brock's hearing loss grades.
resultThe study found 45.23% participants with some degree of hearing loss consequent to multidrug resistant tuberculosis treatment. Around 9.5% of the total participants developed potential disabling hearing loss. Around 30.09% of participants had experienced subjective tinnitus during the course of treatment. Study found no significant association (p-value 0.88, 95%CI 0.93-1.00) between referred test result of DPOAE (distortion product Otoacoustic emission) screener and the ototoxicity.
conclusionStudy showed with significant prevalence of ototoxicity. Since hearing impairment have negative impact on psychosocial wellbeing and communication abilities, it is paramount importance to put in place the various preventative measures. With current guidelines by World Health Organisation on replacement of second-line injectable by oral regimens while treating patients with MDR-TB, it is expected to address ototoxicity and related issues.
