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 Smoking is a major global health concern, linked to numerous medical conditions, including hearing loss and psychological distress. Research suggests that smokers have a significantly higher risk of hearing impairment than non-smokers, possibly due to oxidative stress and vascular damage. Smoking is also associated with psychological effects such as depression, anxiety, and stress, though the relationship is complex. This study aims to compare the prevalence and degree of hearing loss between smokers and non-smokers using pure tone audiometry, and to evaluate the levels of psychological distress (depression, anxiety, and stress) in both groups using the Depression, Anxiety, and Stress Scale-21 (DASS-21) score. It also aims to assess the relationship between smoking frequency and duration with hearing loss and psychological distress. Materials and methods A prospective cross-sectional study was conducted at the ENT Outpatient Department of AIIMS Bhopal over three months. A total of 100 male participants aged 18-55 years were divided into two groups: 50 smokers (current or past) and 50 age- and gender-matched non-smokers. Hearing was evaluated through pure tone audiometry, tuning fork tests, and otoscopy. Psychological distress was assessed using the DASS-21, while nicotine dependence was measured using the Fagerström Test for Nicotine Dependence. Data were analyzed using IBM SPSS Statistics for Windows, Version 21 (Released 2012; IBM Corp., Armonk, NY, USA), applying the Chi-square test, with a significance level of p < 0.05. Results Hearing loss was significantly more prevalent in smokers (18, or 36%) than in non-smokers (7, or 14%) (p = 0.017). However, no statistically significant correlation was found between the severity of hearing loss and the frequency or duration of smoking. Psychological distress was observed in both groups, with depression (10 (20%) vs. 6 (12%)), anxiety (18 (36%) vs. 23 (46%)), and stress (2 (4%) vs. 0%) being more common in smokers, though these differences were not statistically significant. Nicotine dependence varied, with 22 (44%) of smokers having very low dependence, while two (4%) had very high dependence. Higher cigarette consumption was significantly associated with greater nicotine dependence (p < 0.001). Conclusion Smoking is associated with a significantly higher risk of hearing loss, reinforcing the need for awareness and early screening among smokers. However, no strong link was found between smoking and psychological distress in this study. Given the limitations of sample size and study duration, further research is needed to explore the long-term effects of smoking on both hearing and mental health. Smoking cessation programs should incorporate regular hearing assessments and psychological support for better overall well-being.
