Laryngopharyngeal Reflux: Effect of Antireflux PPI Therapy on Nasal Congestion and Olfaction.
Article in Maedica, 2024. 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
objectiveLaryngopharyngeal reflux (LPR) is responsible for many otorhinolaryngology manifestations. There is little evidence regarding the LPR impact on olfaction. No other study has investigated the efficacy of proton pump inhibitors (PPIs) on olfaction. We aimed to evaluate the effect of antireflux medication on olfaction and nasal patency in patients with LPR. MATERIALS AND
methodsThirty patients with LPR were recruited. Nasal symptoms were self-evaluated with NOSE and SNOT-22 surveys, while a taste visual analogue scale (VAS) was used for gustation. Olfaction was evaluated with Sniffin' Sticks test and nasal patency with anterior rhinomanometry. After 12 weeks of oral PPIs, the procedure was re-applied and clinical outcomes were compared.
resultsVariables with statistically significant difference included the olfactory threshold (means 1,87/ SD 3,3/ t -3,11/ p 0,004) and the combined threshold-discrimination-identification (TDI) scores of Sniffin' Sticks test (means -2,61/ SD 5.26/ t -2.75/ p 0.01) and the self-assessment NOSE (p 0.009) and SNOT-22 (0.031) tests. However, no variable concerning nasal patency revealed statistically significant difference before and after treatment in the study group (p 0.677).
conclusionsOral PPIs treatment was associated with better olfactory threshold and TDI scores. These results raise the need for further studies, regarding the effect of antireflux medication on patients suffering from LPR who express nasal symptoms and olfaction disfunction.
