Course of olfaction after sinus surgery for chronic rhinosinusitis.

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: The influence of surgery on olfaction in patients who suffer from chronic rhinosinusitis (CRS) is still not fully understood. Most particularly, the time course of the recovery is poorly studied. Methods: The prospective study describes the results of the Sniffin' Sticks identification test in 41 subjects before (V1), 2 weeks after (V2), and 6 months after (V3) endonasal sinus surgery (ESS). Influencing factors (gender, revision surgery, nasal polyposis, and initial olfactory score) on the changes of the smell testing were evaluated. Results: The whole cohort showed a significant improvement in Identification scores, from 8.63 to 10.24 after 2 weeks and to 10.68 after 6 months. Patients with nasal polyps revealed a similar increase in the identification test at V3 (+2.17 compared to +1.89 in those without polyps) but not at V2 (+1.30 compared to 2.00). The initial classification of olfaction was the only significant influencing factor. Patients who showed initially anosmic results improved (+4.87 at V2 and +4.73 at V3), as did patients in the hyposmic group (+0.58 resp. +1.42). Forty-four percent of the patients reached an improvement with regard to their diagnostic group. Conclusions: This study of the evaluation of the sense of smell after ESS exhibits an improvement of olfaction already 2 weeks after surgery, which is stable for 6 months. CRSwNP and CRSsNP patients showed similar improvements of olfaction, although the recovery was slower in CRSwNP patients. Level of Evidence: 2b.
