1 · What the graph read from 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.

2 · The registry

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

objectivesSmell impairment (SI) is a well-known symptom of chronic rhinosinusitis with nasal polyps (CRSwNP). The aim of study was to analyze olfactory and trigeminal event-related potentials (OERPs/TERPs) and psychophysical smell tests in subjects with CRSwNP, and its potential role in clinical practice.

methodsProspective study included 57 subjects. Two investigated groups with CRSwNP and one control group. Group I (n = 20) contained subjects without CRSwNP before septoplasty. Group II (n = 18) contained subjects with CRSwNP without therapy. Group III (n = 19) contained subjects with CRSwNP after intranasal corticosteroid therapy. Sniffin stick identification smell test and OERPs/TERPs were performed in all subjects.

resultsAccording to the psychophysical smell test, SI was detected in 65% of subjects with CRSwNP. In the control Group I (without CRSwNP), the absence of OERPs was 5.0%, whilethe mean absence rate in Groups II, III (with CRSwNP) was 8.1%. The highest percentage of absence of OERPs was registered in Group II (11.1%). Absence of TERPs was detected in an average of 21.6% of CRSwNP subjects. Group III showed the highest percentage of absence of TERPs (32%). In the control Group I, TERPs were absent in 0% of subjects.

conclusionCRSwNP significantly impairs olfactory function compared to patients without CRSwNP, Absence of TERPs was detected in an average of 21.6% of CRSwNP subjects versus healthy controls (0%). Presence of TERPs appears to be a predictor of preservation of olfactory function.
