Atopic dermatitis and chronic sinusitis: a two-sample Mendelian randomized study.
Article in Brazilian journal of otorhinolaryngology. 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
objectivesDespite observational studies have indicated a potential association between Atopic Dermatitis (AD) and Chronic Sinusitis (CRS), it is uncertain whether there is a causal relationship between AD and CRS. To address this ambiguity, a two-sample bidirectional Mendelian randomization methodology was utilized to examine the potential causal association between AD with CRS.
methodsThe summary data for the Genome-Wide Association Study (GWAS) on AD and CRS were sourced from the FinnGen consortium. To investigate the causal link between AD and CRS, we applied several approaches, including Inverse-Variance Weighting (IVW), MR-Egger regression, weighted median, simple mode, and weighted mode methods. Furthermore, the heterogeneity, horizontal pleiotropy, and sensitivity were investigated using several methods.
resultsBased on the random-effect IVW approach, results showed a 15.8% increased risk of CRS in those with AD compared with non-AD populations (p = 7.771e-07, OR = 1.158, 95% CI 1.092-1.227). Inversely, there was no direct evidence that CR increased the risk of AD (p = 0.979, OR = 1.001, 95% CI 0.908-1.104). The MR-Egger intercept test results indicated an absence of horizontal pleiotropy in this study (AD: p = 0.381; CRS: p = 0.144). Additionally, the leave-one-out test demonstrated the results of both forward and backward analyses were reliable and robust.
conclusionOur study confirmed the causal effect of AD on CRS, with AD increasing the risk of developing CRS. Conversely, CRS did not affect the risk of developing AD. Our study suggested that in the prevention and treatment of CRS, physicians cannot ignore the impact of AD on CRS. LEVEL OF EVIDENCE: Level 2.
