Correlation of fraction of exhaled nitric oxide with asthma control test and asthma severity in diagnosed cases of asthma.
Article in Medical journal, Armed Forces India, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background: Fraction of NO in exhaled air (FENO) has emerged as a simple, non-invasive, sensitive marker of airway inflammation in asthma diagnosis and management. Correlation studies of FENO with clinical grades of asthma and symptom burden are sparse, more so in Indian population. Hence, this study was carried out in Indian subjects to evaluate FENO correlation with asthma severity. Methods: The study was performed on 52 proven cases of asthma in the age group of 17-90 years in period of December 2016 to May 2018. All the subjects had assessment in the form of Asthma Control Test (ACT)questionnaire, FENO parts per billion measurement with a portable NO analyzer (NIOX MINO Airway Inflammation Monitor; Aerocrine) and spirometry. Statistical analysis was presented in the form of percentage (%) and mean. Results: Of a total of 52 asthma cases, 27 (51.9%) were male cases while 25 (48.1%) were female cases. Study population ranged from 17 to 82 years. Subjects categorized into 03 categories of asthma severity based on their treatment step. ACT score of ranged between 11 and 25 with a mean value of 20.27 and standard deviation of 3.73. No significant correlation was found between FENO and ACT (r) = -0.177, P-value = 0.210 (>0.05). Significant correlation between FENO and different grades of asthma severity was found with p-value 0.032 (<0.05). Conclusion: Asthma severity as assessed by the step of treatment is correlated well with FENO value in an asthmatic individual to maintain the controlled asthma status. FENO and ACT were found to have no correlation.
