Eosinophilic and Non-eosinophilic Chronic Rhinosinusitis with Nasal Polyps and Their Clinical Comparison in Indian Population.
Article in Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis 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
Eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) and non-eosinophilic chronic rhinosinusitis with nasal polyps (neCRSwNP) are two distinct endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP). The aim of the study was to find the prevalence of eCRSwNP and neCRSwNP, their clinical comparison and to establish predictive values for clinical and diagnostic factors to differentiate between eCRSwNP and neCRSwNP in Indian population with CRSwNP. This study was a prospective cohort, multi- institutional study. A total of 162 patients who were diagnosed with nasal polyps at different military hospitals in India during the period from 2011 to 2020 were selected for study. They were diagnosed in accordance with EPOS guidelines. They were randomly divided into two groups as eCRSwNP and neCRSwNP based on the response to oral corticosteroids for 2 weeks duration and the prevalence of eCRSwNP was established. Blood samples were collected and endoscopic sinus surgery was performed in all patients after atleast 2 months of last steroid dose. Preop CT scan scores, preop nasal endoscopy scores, preop blood eosinophil counts, preop tissue eosinophil counts were compared between the groups. Postop followup was done at 6 months by comparing CT scan scores and nasal endoscopy scores. Predictive values for clinical and diagnostic factors were established to diagnose eCRSwNP in Indian population. Out of a total 162 patients, 121 (74.6%) patients were classified into eCRSwNP and 41 (23.6%) into neCRSwNP out of a total of 162 patients with CRSwNP. CRSwNP was seen in the 4th decade. eCRSwNP was seen in the later part and neCRSwNP was seen in the early part. eCRSwNP was more common in males and neCRSwNP was more common in females. Smoking, asthma and aspirin intolerance were more commonly seen in eCRSwNP than neCRSwNP,
