Trial report in Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology, 2026. 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
objectivesThis study comprehensively compares the differences between concealable traction hook spherical buccal tubes (concealable spherical tubes) and conventional rectangular buccal tubes in terms of patient comfort, incidence of buccal mucosal injury, periodontal health indices, and clinical bond failure rate to provide evidence for clinical application.
methodsThirty subjects were enrolled and treated using a split-mouth design, where the two sides of each patient's oral cavity were randomly assigned to receive either conventional rectangular buccal tubes (group A) or concealable spherical buccal tubes (group B). During treatment, pain scores, ulcer occurrence, and bond failure of the first molar buccal tubes were recorded. Periodontal indices, including plaque index (PLI), gingival index (GI), and sulcus bleeding index (SBI) of the first molars, were assessed before treatment (T0) and 30 days after tube bonding (T1).
resultsThe pain scores in group A were significantly higher than those in group B (
conclusionsThe clinical performance of concealable spherical buccal tubes is significantly superior to that of conventional rectangular buccal tubes in improving patient comfort, reducing the incidence of mucosal injury and clinical bond failure, and maintaining periodontal health. This design offers patients a more comfortable and healthier orthodontic treatment experience.
