Efficacy and safety of the tree sublingual immunotherapy tablet in the subpopulation of Canadian children with allergic rhinitis and/or conjunctivitis: phase III trial results.
Article in Allergy, asthma, and clinical immunology : official journal of the Canadian Society of Allergy and Clinical Immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04878354 (Efficacy and Safety of the SQ Tree Sublingual Immunotherapy Tablet in Children and Adolescents With Moderate to Severe Allergic Rhinitis and/or Conjunctivitis Induced by Pollen From Birch and Trees Belonging to the Birch Homologous Group), which is not on this 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.

Abstract
backgroundPollen from birch and other trees in the birch homologous group (e.g., oak) is a common trigger of allergic rhinitis and/or conjunctivitis (AR/C) in Canada. The efficacy and safety of the tree sublingual immunotherapy (SLIT)-tablet in children with AR/C was evaluated post hoc in the Canadian subpopulation of a phase III, double-blind trial (EudraCT2020-004372-17).
methodsChildren and adolescents aged 5-17 years with moderate-to-severe tree AR/C were randomized to either daily tree SLIT-tablet or placebo for up to 52 weeks. Participants had free access to symptom-relieving medication. The primary endpoint was the average total combined score (TCS; sum of rhinoconjunctivitis daily symptom score [DSS] and daily medication score [DMS]) during birch pollen season (BPS). Average TCS during tree pollen season (TPS, consisting of birch, alder, hazel, and oak pollen seasons), oak pollen season (OPS), and pure OPS (excluding days from birch, alder, or hazel pollen seasons) were also analyzed.
resultsIn the Canadian subpopulation (n = 87), treatment with the tree SLIT-tablet reduced the average TCS by 26.8% versus placebo during BPS (absolute difference [95% CI] = 1.89 [-0.71, 4.49], p = 0.138), 32.0% during TPS (absolute difference = 2.14 [-0.03, 4.32], p = 0.042), 46.6% during OPS (absolute difference = 3.70 [0.98, 6.42], p = 0.004), and 50.6% during pure OPS (absolute difference = 4.20 [1.12, 7.27], p = 0.005). Reductions in DSS and DMS with tree SLIT-tablet versus placebo were also observed. In the total trial population (N = 952), tree SLIT-tablet treatment reduced the average TCS by 19.2% versus placebo during BPS (absolute difference = 1.13 [0.42, 1.84], p = 0.002), 16.8% during TPS (absolute difference = 0.76 [0.26, 1.26], p = 0.003), 23.4% during OPS (absolute difference = 1.32 [0.60, 2.05], p < 0.001), and 19.9% during pure OPS (absolute difference = 1.03 [0.27, 1.80], p = 0.009). The tree SLIT-tablet was well tolerated in the total trial and Canadian subgroup populations.
conclusionsThe tree SLIT-tablet demonstrated favorable efficacy and was well tolerated in Canadian children and adolescents with AR/C. CLINICAL
