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
objectiveThe data on epidemiological features of interstitial lung diseases (ILD) in the Gulf region are scarce. The aim of this study was to describe the baseline clinical and epidemiological characteristics of ILD patients in a single specialized expertise center in Kuwait. SUBJECTS AND
methodsThis prospective, observational registry evaluated 167 patients newly diagnosed with ILD via a multidisciplinary team approach between November 2016 and October 2025. The demographics, exposures, comorbidities, and physiological data were systematically collected. Appropriate parametric and nonparametric descriptive statistics were applied to summarize and compare clinical variables across ILD subtypes.
resultsMajority of the patients were male (60.5%), with a mean age of 58.7 years (SD ± 13.2). Idiopathic pulmonary fibrosis (IPF) was the most frequent subtype (34.1%), followed by connective tissue disease-related ILD (CTD-ILD; 23.4%) and hypersensitivity pneumonitis (HP; 20.4%). The environmental and occupational exposures were documented in 41.3% and 10.2% of the cohort, respectively, with environmental exposure predominant in the HP group (76.5%). Overall, gastroesophageal reflux disease was the most prevalent comorbidity (in 58.1% of cases). Patients with HP demonstrated the poorest baseline lung function compared to other subtypes, with a mean predicted forced vital capacity of 59.2% (SD ± 14.4).
conclusionThis 9-year prospective study provides the first real-world ILD dataset from Kuwait. IPF, CTD-ILD, and HP are the predominant clinical phenotypes. Knowledge of comprehensive exposure histories is vital for diagnostic evaluation to identify manageable HP before irreversible fibrosis develops.
