Lung function improvement following smoking cessation in chronic respiratory conditions: A meta-analytic approach.

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
IntroductionSmoking is a major contributor to the development and progression of chronic respiratory diseases. Although cessation is known to improve general health, its direct impact on pulmonary function remains debated. This meta-analysis aimed to evaluate the effects of various smoking cessation interventions on lung function outcomes in patients with chronic respiratory diseases.MethodsA systematic search of PubMed, Scopus, and Web of Science was conducted to identify eligible clinical trials. Standardized mean differences with 95% confidence intervals were calculated to compare changes in forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and the FEV1/FVC ratio.ResultsFourteen studies were included in the study. Smoking cessation was associated with a marginal improvement in FEV1 (standardized mean difference = 0.23; 95% confidence interval: -0.00 to 0.47;
