Modulators of Airway Remodeling: The Role of Caffeine and Calcitriol.
Article in International journal of molecular sciences, 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
Airway remodeling is a process that occurs in chronic obstructive diseases, such as asthma and COPD. It is associated with adverse changes in the structure and function of the airways. An increasing amount of literature points to the potential protective effects of vitamin D and caffeine against inflammation and fibrosis. The aim of the study is to evaluate the effect of calcitriol and caffeine on the expression of genes and proteins associated with airway remodeling. The Calu-3 cell line was treated with TGF-β, calcitriol, and caffeine in different combinations. Subsequently, the expression of VDR, CDH1, VIM, MMP-2, and MMP-9 were examined at the mRNA and protein levels using real-time PCR and Western blot, respectively. One-way analysis of variance was used to determine differences in several groups. Both calcitriol and caffeine were associated with a decrease in the expression of
