Relationship between diabetes-related clinical characteristics and preserved ratio impaired spirometry (PRISm): findings from NHANES 2007-2012.

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
Introduction: To analyse the relationship between diabetes, its severity (including blood glucose levels, disease duration, antidiabetic drug use and number of comorbidities) and preserved ratio impaired spirometry (PRISm) using data from the National Health and Nutrition Examination Survey (NHANES). Methods: This cross-sectional study collected data from the NHANES database from 2007 to 2012. PRISm was defined as having a forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) ratio ≥0.7 and an FEV1 predicted value <80%. We examined the relationship between diabetes duration, fasting plasma glucose (FPG), glycated haemoglobin (HbA1c), log-transformed homeostasis model assessment for insulin resistance, C reactive protein and the number of comorbidities with PRISm in the entire population. We analysed the relationship between antidiabetic drug use and PRISm, specifically in the diabetes population. Logistic regression models were used, and results were reported as OR. Results: A total of 5783 participants with normal spirometry or PRISm were included in the analysis. Diabetes was associated with 2.19 times higher odds of PRISm compared with non-diabetic participants. Longer disease duration increased PRISm odds by 2% per year. Each 1-unit increase in HbA1c and each 10 mg/dL increase in FPG were associated with 24% and 6% higher odds of PRISm, respectively. No relationship was found between insulin resistance and PRISm after adjusting for covariates. An increase of 1 mg/dL in CRP was associated with 18% higher odds of PRISm. A higher number of diabetes-related comorbidities was strongly associated with PRISm. No significant relationship was found between antidiabetic drug use and PRISm. Conclusions: Severe diabetes status, such as higher blood glucose levels, longer disease duration and a greater number of comorbidities, is associated with an increased risk of PRISm. Effective blood glucose control, self-management and regular monitoring of lung function are crucial for diabetes management.
