Activities and concentration of alpha-1 antitrypsin and cystatin C in serum from patients with house dust mite asthma.
Article in Asia Pacific allergy, 2023. 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
Background: The proteolytic activities of house dust mite (HDM) allergens are involved in the pathogenesis of asthma by cleaving T-junction protein complexes, increasing the permeability of airway epithelial cells, and enabling the allergens to reach the interstitial tissue. The human body contains natural protease inhibitors such as alpha-1 antitrypsin (AAT) with antiserine protease activity and cystatin C with anticysteine protease activity. Objective: This study aimed to investigate the behavior of serum AAT and cystatin C levels in patients with HDM-allergic asthma. Methods: Ten individuals with HDM-allergic asthma and 10 healthy volunteers participated in a cross-sectional study. The serum AAT and cystatin C inhibitory activities were measured using enzymatic assays. ELISA was used to determine the serum AAT and cystatin C concentrations. Results: Serum AAT inhibitory activity ( Conclusion: These findings suggest that serum cystatin C activity is involved in asthma pathogenesis. Additional research is required to address this issue.
