Clinical characteristics and treatment outcomes of pediatric achalasia: a 10-year experience from a tertiary center in Iran.
Article in BMC research notes, 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
objectiveThis study aimed to examine demographic patterns, clinical presentation, diagnostic methods, and therapeutic outcomes of achalasia patients in a tertiary hospital in Tehran, Iran. We conducted a retrospective study of patients aged < 18 years with a diagnosis confirmed by barium swallow and endoscopy; those with other diagnoses or incomplete data were excluded.
resultsWe included 100 patients (59 boys, 41 girls; mean age: 7.45 ± 4.58 years, range: 4 months - 16 years) diagnosed between 2013 and 2022. The most common symptoms were dysphagia (83%), nausea/vomiting (78%), and weight loss (49%). The mean diagnostic delay was 22.04 ± 32.75 months. Comorbid conditions were present in 23% of the patients, most commonly esophageal atresia and Allgrove syndrome. The classic bird's beak sign was seen in 61% of the barium images. 95% of the patients went through pneumatic dilatation (PD), and a successful response to PD was defined as clinical improvement and resolution of dysphagia. 31.6% of them responded to a single PD session, while 68.4% required multiple PD sessions or Heller myotomy. Younger age was significantly associated with the need for multiple PD sessions (p = 0.001). No major complication was seen.
