Magnesium alginate versus proton pump inhibitors for the treatment of laryngopharyngeal reflux: a non-inferiority randomized controlled trial.
Trial report in European archives of oto-rhino-laryngology : official journal of the European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino-Laryngology - Head and Neck Surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 4 of them syntheses that pooled it.
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
purposeProton pump inhibitors (PPIs) are commonly prescribed for laryngopharyngeal reflux (LPR), but their efficacy remains debated. Alginates is an option for the treatment of LPR with few adverse effects. The study aimed to investigate the non-inferiority of an alginate suspension (Gastrotuss
methodsA non-inferiority randomized controlled trial was conducted. Fifty patients with laryngopharyngeal symptoms (Reflux Symptom Index -RSI- ≥ 13) and signs (Reflux Finding Score -RFS- ≥ 7) were randomized in two treatment groups: (A) Gastrotuss
resultsGroups had similar RSI and RFS scores at baseline. From pre- to 2-month posttreatment, the mean RSI significantly decreased (p = 0.001) in alginate and PPI group (p = 0.003). The difference between groups in the RSI change was not significant (95%CI: - 4.2-6.7, p = 0.639). The mean RFS significantly decreased in alginate (p = 0.006) and PPI groups (p = 0.006). The difference between groups in the mean change RFS was not significant (95%CI: - 0.8; 1.4, p = 0.608).
conclusionAfter 2 months of treatment, LPR symptoms and signs are significantly reduced irrespective of the treatment. Alginate was non-inferior to PPIs and may represent an alternative treatment to PPIs for the treatment of LPR.
