Isolated Fractures of the Nose Are Associated with Olfactory Impairment.

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
introductionMany studies investigated olfactory function following head trauma, but surprisingly few studies looked at smell loss following fractures of the nose. The aim of this study was to examine whether isolated fractures of the nose are associated with olfactory dysfunction.
methodsA total of 97 participants (49 patients in the fracture group, 48 participants in the control group) were included in this cross-sectional study. The fracture and control groups were matched in terms of gender and age. Time since fracture varied, starting from 28 days to a maximum of 2 years. Olfaction was tested using the "Sniffin' Sticks" test battery (odour threshold, discrimination, and identification) and further data were collected using a basic questionnaire as well as via ENT examination with nasal endoscopy.
resultsCompared to controls, the scores for odour discrimination and odour identification were lower in the fracture group (mean odour identification: 11.5 vs. 12.8; mean odour discrimination: 11.2 vs. 12.6; p < 0.05). Odour thresholds were also decreased in the trauma group (mean odour thresholds: 6.8 vs. 8.1; p = 0.06). General olfactory function scores (TDI score) correlated negatively with the time since fracture (p < 0.001), possibly indicating further decrease of function following trauma.
conclusionFractures of the nose are associated with a decrease in olfactory function, which is found especially for odour discrimination and odour identification.
