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: The change in FEV Aim: The aim of the present study was to estimate the presence of reversibility among the patients of obstructive airway disease and to identify the factors affecting it. Methods: Patients who presented to the department of respiratory medicine with symptoms of dyspnea were evaluated with spirometry. Spirometry and post bronchodilator reversibility (BDR) was defined as per international guidelines. SPSS 17 was used for statistical analysis and P < 0.05 was considered significant. Results: Out of 100 patients studied, 33 had BDR. Median age of the population was 58 ± 17 years. There were 72 non-smokers and 58 men. A total of 32 had chronic obstructive pulmonary disease (COPD), 56 had asthma, and 12 had normal spirometry. The median pre and post bronchodilator FEV1 was 1.34L/Sec and 1.46 L/sec respectively. Twenty-seven of asthma (41%) and 6 of COPD (19%) had BDR (P = 0.05). Other factors associated with BDR were smoking (P = 0.035). There was no statistically significant correlation found between eosinophilia, gender, severity of obstruction, BMI, height, weight and age. Conclusion: The prevalence of post BDR in the study population was 33%. The factors affecting BDR were smoking status, and asthma. The study did not show any significant correlation between BDR and eosinophilia, gender, height and age.
