Comparison of nasal patency after nose-blowing between pinch versus no pinch method: a randomized controlled trial.
Trial report in Scientific reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
We proposed that nose-blowing without pinching was safer and able to get rid of mucus and maintain nasal patency as effective as the pinch and blow method. The objective of this study was to evaluate the nasal patency after nose-blowing by pinching the nose versus no pinching. The patients who have nasal discharge such as allergic rhinitis or common cold were recruited. The patients were randomized to perform pinching or no pinching nose-blowing. Fifty patients were enrolled in this study. The objective evaluation using acoustic rhinometry found no difference in nasal patency between the two groups (p > 0.05). The subjective patency score was significantly higher in the pinch one nostril shut group (mean difference 0.88, 95% CI 0.20-1.55). The patency of the two methods were comparable according to the objective test. However, the patients felt that their nose was clearer when pinching and blowing.
