Association Between Allergic Rhinitis and Children With Appendectomy-A Nationwide Population-Based Retrospective Cohort Study.
Article in Health science reports, 2025. 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 and Aims: The appendix plays an important role to the human intestinal microbiota and immunity. Thus, appendectomy may alter immune function and intestinal biofilm. Allergic rhinitis is a common disease which is due to imbalance of TH2/TH1 cells and cytokine. The aim of this study was to evaluate the risk of allergic rhinitis after appendectomy in children. Methods: The data source was the National Health Insurance Research Database (NHIRD), which is a large, population-based database in Taiwan. We collected 4013 patients who had undergone appendectomy (case group) between January 1, 2000 and December 31, 2018 and matched them with 16,052 patients who had not undergone appendectomy (control group) by sex and age using proportional propensity score (PSM) at a ratio of 1:4 after excluding patients with a diagnosis of allergic rhinitis in the year prior to appendectomy. In addition, Poisson regression and subgroup analyses were used to investigate the relative risk of the development of allergic rhinitis after appendectomy in children. Results: The relative risk of subsequent allergic rhinitis in patients who had undergone appendectomy was found to be higher (RR = 1.24; Conclusion: Appendectomy was correlated with a 1.24-fold increased risk of developing allergic rhinitis in children, especially within 5 years of follow-up. Therefore, we suggest that the indication of appendectomy should be carefully evaluated to decide the best way to treat acute appendicitis.
