Timothy Grass Pollen-Specific Immunoglobulin E in Nasal Secretions During Natural Allergen Exposure and After a Nasal Provocation Test in Patients with Suspected Local Allergic Rhinitis.

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
introductionAllergic rhinitis (AR) imposes a substantial burden on individuals worldwide. Local allergic rhinitis (LAR) patients exhibit symptoms similar to those of AR without a positive skin prick test (SPT) or the presence of sIgE specific to one or more allergens. Our study evaluated specific and total grass pollen IgE in the nasal secretions of patients with suspected LAR, examining the effects of natural pollen exposure and nasal provocation testing (NPT).
methodsTwenty-nine subjects (18 with suspected LAR and 11 with AR) were included in this study. The total nasal symptom score (TNSS) and visual analog scale (VAS) were used for subjective assessment. NPT was performed using grass pollen allergen. Nasal lavage was used to obtain nasal secretions, and the levels of sIgE and total IgE were measured.
resultsDuring the exposure vs. the off-exposure period, the TNSS and VAS were significantly higher in LAR (
conclusionsThe assessment of local sIgE levels in nasal secretions can be used as a method for the diagnostic workup of patients with suspected LAR. Achieving a well-defined and standardized protocol for the assessment of sIgE concentrations in nasal secretions of LAR is a goal of future larger studies.
