Corticosteroid therapy in chronic rhinosinusitis with nasal polyps: from histopathological tissue remodeling to patient adherence and barriers.
Article in Romanian journal of morphology and embryology = Revue roumaine de morphologie et embryologie. 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
BACKGROUND AND
objectivesThis study evaluated mucosal remodeling across different corticosteroid regimens and identified barriers to treatment adherence in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). PATIENTS, MATERIALS AND
methodsWe enrolled 56 consecutive patients divided into two arms: Group 1 (n=22) underwent sinus surgery after topical, systemic, or combined corticosteroid therapy, with mucosal biopsies evaluated via a four-parameter histopathological (HP) score (infiltrate, eosinophils, edema, fibrosis). Group 2 (n=34; 15 excluded due to systemic steroid use) received exclusive medical treatment and was assessed for compliance using the Medication Adherence Questionnaire (MAQ) at baseline and three months.
resultsIn Group 1, combined therapy (topical and systemic) demonstrated significantly lower HP scores compared with the topical-only group for inflammatory infiltrate (p=0.0280), tissue eosinophils (p=0.036), intramucosal edema (p=0.0400), and fibrosis (p=0.0393). In Group 2, a strong negative correlation was established between MAQ and Medication Adherence Report Scale-5 (MARS-5) (r=-0.9216, p<0.0001), confirming validity. Early treatment discontinuation and time constraints were the primary drivers of non-adherence.
conclusionsCombined topical and systemic corticosteroid therapy yields superior tissue remodeling outcomes by significantly reducing mucosal inflammation, eosinophilia, edema, and fibrosis compared to topical therapy alone. The MAQ is a valid clinical tool, highlighting early discontinuation and time constraints as key targets to optimize patient compliance and CRSwNP management.
