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
Background: Hearing aids are the most common conventional devices used to manage sensorineural hearing loss. Although safe and reliable methods, Hearing aids have some minor or moderate side effects that may be inconvenient for those patients and may result in patient non-compliance or even abandonment of their usage. One of the most common is ear irritation and itching. Although itching is attributed to several causes including athetosis and skin allergy, however, Both Bacterial and fungal infections are considered the major leading cause. This study aims to determine the microbiological profile of the external ear in hearing-aided patients presented with itching. Methods: 150 hearing-aided patients presented with itching were recruited for the study all underwent history taking, full clinical examination, and external canal swabs were taken. Then swabs were cultivated for both bacterial and fungal growth. Results: 15 samples (8.6%) were free from infection while 159 samples (91.4%) were positive for infection. There was a statistically significant difference between the free and infected samples (either bacterial or fungal). Out of the infected samples, 135 samples (77.6%) had a bacterial infection and 24 samples (13.8%) had a fungal infection. Conclusion: Microbial growth is the major factor in the development of external ear itching and pruritis, being mainly staphylococcal infection either staphylococcus Aureus or coagulase-negative species, however, gram-negative bacteria and fungal infection are not considered uncommon. The duration of hearing aid usage was found significant in the development of such infection. These findings shed light on the importance of frequent cleaning of both the external ear molds and proper hygiene of the external canal.
