An experimental study on the pollen particle blocking efficacy of a barrier nasal mask.

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
Objective: To explore the blocking effect of a barrier nasal mask composed of bionic nasal hair combined with a blocking gel on allergen particles in a 1:1 3D-printed nasal cavity model and to provide new ideas for the clinical prevention and treatment of allergic rhinitis. Methods: A 1:1 scale 3D-printed nasal cavity model was constructed, and dust-free paper was placed at specific anatomical locations within the model. The experimental group was defined as those wearing a nasal mask, whereas the control group did not wear a nasal mask. A simple breathing bag was used to simulate normal respiration, and a pneumatic nebulizer was employed to introduce stained Results: At 15 min, the median (25th, 75th percentiles) total scores for all anatomical sites in the nonblocking group and blocking group were 3 (2, 4) and 0 (0, 1), respectively ( Conclusion: This barrier nasal mask can effectively reduce pollen particle deposition at various anatomical sites in the nasal cavity. The crossover test using the same model verified the reliability of its blocking efficacy, which suggests that it is a potential innovative intervention for the prevention of allergic rhinitis.
