The prevalence of olfactory dysfunction in chronic rhinosinusitis.
Synthesis in The Laryngoscope, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 70 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
objectivesMany studies have reported that olfactory dysfunction frequently occurs in chronic rhinosinusitis (CRS) populations; however, the prevalence and degree of olfactory loss has not been systematically studied. The aims of this study were to use combined data to report the prevalence of olfactory dysfunction and to calculate weighted averages of olfactory test scores in CRS patients. DATA SOURCES: A search was conducted in PubMed and Scopus, following the methods of Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. REVIEW
methodsStudies reporting the prevalence of olfactory dysfunction using objective measures or olfactory test scores using validated scales were included.
resultsA total of 47 articles were included in a systematic review and 35 in the pooled data analysis. The prevalence of olfactory dysfunction in chronic rhinosinusitis was found to be 30.0% using the Brief Smell Identification Test, 67.0% using the 40-item Smell Identification Test, and 78.2% using the total Sniffin' Sticks score. Weighted averages ± standard deviation of olfactory test scores were 25.96 ± 7.11 using the 40-item Smell Identification Test, 8.60 ± 2.81 using the Brief Smell Identification Test, 21.96 ± 8.88 using total Sniffin' Sticks score, 5.65 ± 1.51 using Sniffin' Sticks-Threshold, 9.21 ± 4.63 using Sniffin' Sticks-Discrimination, 9.47 ± 3.92 using Sniffin' Sticks-Identification, and 8.90 ± 5.14 using the Questionnaire for Olfactory Disorders-Negative Statements.
conclusionsIn CRS populations, a significant percentage of patients experience olfactory dysfunction, and mean olfactory scores are within the dysosmic range. Laryngoscope, 2016 127:309-320, 2017.
