Esophageal dysphagia and reflux symptoms before and after oral IQoro(R) training.
Trial report in World journal of gastroenterology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimTo examine whether muscle training with an oral IQoro(R) screen (IQS) improves esophageal dysphagia and reflux symptoms.
methodsA total of 43 adult patients (21 women and 22 men) were consecutively referred to a swallowing center for the treatment and investigation of long-lasting nonstenotic esophageal dysphagia. Hiatal hernia was confirmed by radiologic examination in 21 patients before enrollment in the study (group A; median age 52 years, range: 19-85 years). No hiatal hernia was detected by radiologic examination in the remaining 22 patients (group B; median age 57 years, range: 22-85 years). Before and after training with an oral IQS for 6-8 mo, the patients were evaluated using a symptom questionnaire (esophageal dysphagia and acid chest symptoms; score 0-3), visual analogue scale (ability to swallow food: score 0-100), lip force test (≥ 15 N), velopharyngeal closure test (≥ 10 s), orofacial motor tests, and an oral sensory test. Another twelve patients (median age 53 years, range: 22-68 years) with hiatal hernia were evaluated using oral IQS traction maneuvers with pressure recordings of the upper esophageal sphincter and hiatus canal as assessed by high-resolution manometry.
resultsEsophageal dysphagia was present in all 43 patients at entry, and 98% of patients showed improvement after IQS training [mean score (range): 2.5 (1-3) vs 0.9 (0-2), P < 0.001]. Symptoms of reflux were reported before training in 86% of the patients who showed improvement at follow-up [1.7 (0-3) vs 0.5 (0-2), P < 0.001). The visual analogue scale scores were classified as pathologic in all 43 patients, and 100% showed improvement after IQS training [71 (30-100) vs 22 (0-50), P < 0.001]. No significant difference in symptom frequency was found between groups A and B before or after IQS training. The lip force test [31 N (12-80 N) vs 54 N (27-116), P < 0.001] and velopharyngeal closure test values [28 s (5-74 s) vs 34 s (13-80 s), P < 0.001] were significantly higher after IQS training. The oral IQS traction results showed an increase in mean pressure in the diaphragmatic hiatus region from 0 mmHg at rest (range: 0-0 mmHG) to 65 mmHg (range: 20-100 mmHg).
conclusionOral IQS training can relieve/improve esophageal dysphagia and reflux symptoms in adults, likely due to improved hiatal competence.
