Asthma and increased carotid intima-media thickness: A systematic review and meta-analysis.
Synthesis in Biomolecules & biomedicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Asthma has been associated with early vascular changes that elevate the risk of atherosclerosis and cardiovascular diseases. Carotid intima-media thickness (CIMT) serves as a non-invasive marker for subclinical atherosclerosis and cardiovascular risk. However, existing literature presents conflicting results regarding CIMT measurements in asthmatic patients. This study aims to evaluate whether CIMT is elevated in asthma patients compared to healthy controls and to explore potential modifiers. We conducted a systematic review following PRISMA guidelines, performing a literature search across PubMed, Web of Science, ScienceDirect, and the WHO VHL. We calculated pooled standardized mean differences (SMD) with 95% confidence intervals (CI) to assess the differences in CIMT values. Heterogeneity was evaluated using the I² statistic, and subgroup analyses and meta-regression were utilized to identify sources of heterogeneity. Our review included a total of 10 studies. The analysis indicated significantly higher CIMT values in asthma patients compared to healthy controls, with a pooled SMD of 0.65 (95% CI: 0.19 to 1.12, p = 0.005). A limited number of studies addressed various factors, such as disease severity and the use of inhaled corticosteroids, which may influence CIMT measurements. Notably, asthmatic patients, particularly children and adolescents, exhibited higher CIMT values compared to healthy controls, suggesting a potential association with subclinical atherosclerosis in this demographic. However, these findings should be interpreted with caution due to the observational nature of the included studies and the risk of residual confounding. Further longitudinal research is necessary to elucidate the effects of disease characteristics and treatment on vascular health.
