Evaluation of atelocollagen implant therapy for a rabbit model of acquired tracheomalacia following tracheostomy.
Article in Pediatric surgery international, 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
purposeThis study evaluated whether local atelocollagen gel administration prevented airway collapse in a rabbit model of acquired tracheomalacia after tracheostomy.
methodsJapanese white rabbits (≥ 20 weeks) underwent anterior resection of the second-fourth tracheal rings with mucosal preservation. Group A received 1 mL of 3% atelocollagen around the trachea, whereas Group B was untreated. Bronchoscopy was performed preoperatively (Term 1), immediately postoperatively (Term 2), and 3-4 months postoperatively (Term 3). The tracheal lumen area was measured using negative-pressure suction.
resultsSix of seven rabbits in Group A and five of six rabbits in Group B survived. At 30 cmHg, lumen area (%) in Group A was 90.1 ± 19.9 (Term 1), 48.0 ± 40.4 (Term 2), and 69.0 ± 50.3 (Term 3), versus 99.4 ± 7.8, 53.4 ± 20.0, and 15.0 ± 18.8 in Group B. No differences were observed at Terms 1 or 2. At Term 3, lumen area decreased with increasing suction in Group B but was relatively preserved in Group A. Lumen area ≥ 50% at 30 cmHg was observed in 4/6 (66.7%) in Group A and 0/5 (0%) in Group B.
conclusionLocal atelocollagen administration may attenuate airway collapse in tracheomalacia at 3-4 months.
