Incidence of upper respiratory tract infections with biological therapies in moderate to severe atopic dermatitis: a systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 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
Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin condition affecting 5%-20% of children and 2%-10% of adults worldwide. Treatment for moderate-to-severe AD includes biologics like dupilumab, tralokinumab, lebrikizumab, and JAK inhibitors (abrocitinib, upadacitinib). However, upper respiratory tract infections (URTIs) are commonly reported adverse events for these therapies. This meta-analysis aims to estimate the pooled incidence of URTIs associated with these treatments compared to topicals. Methods: A systematic search was conducted across PubMed, MEDLINE, DOAJ, and ClinicalTrials.gov for randomized controlled trials (RCTs) involving AD patients treated with dupilumab, tralokinumab, lebrikizumab, abrocitinib, or upadacitinib, excluding studies of patients treated with topicals, Studies on other dermatitis types and biologics. Data on URTI events, sample sizes, and incidence were extracted. Study quality was assessed using the Cochrane Risk of Bias Tool (RoB 2). A random-effects meta-analysis was conducted using the Netmeta package in R, calculating odds ratios (ORs) with 95% confidence intervals (CIs). Results: From 413 retrieved records, 21 studies met the inclusion criteria. URTI incidence of the treatment group in the included studies ranged from 0.35% to 41.5%, while control groups showed rates between 0% and 40%. Across all studies, URTI incidence was 9.70% in intervention groups and 8.03% in placebo groups (MH OR = 1.18, 95% CI: 0.98-1.42). Heterogeneity was low ( Conclusion: While URTIs are common adverse events for AD therapies, their incidence in intervention groups is similar to control, suggesting no significant increase in risk. These findings provide critical insights for clinicians in balancing efficacy and safety when selecting therapies for AD patients. Further research should explore patient-specific risk factors for URTIs. Systematic review registration: Prospero registration code: [392093].
