Evaluation of Olfactory Bulb Volumes in Patients With Rheumatoid Arthritis: A Retrospective Study.
Article in Archives of rheumatology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: This study aims to evaluate olfactory bulb (OB) volume in patients with rheumatoid arthritis (RA) using magnetic resonance imaging. Patients and methods: In this retrospective and case-control study, OB volumes of 37 RA patients (6 males, 31 females; mean age 48.6±10.8 years; range, 18 to 65 years) were compared with those of 36 healthy control subjects (5 males, 31 females; mean age 46.5±6.9 years; range, 22 to 62 years). OB images were gained with a protocol of 256×256 matrix and a 24-cm field of view, repetition time=5000 milliseconds (TR 5000 msec), echo time=130 milliseconds (TE 130 msec), number of excitations=2 (NEX 2) and a 5 mm slice thickness. OB volume was computed with the aid of the above images using three dimensional views. The surface of each slice area was calculated in mm2 and all surfaces were added and multiplied by front-back length to obtain a volume in mm3. Results: Left (70.5±14.4 vs. 91.1±12.2 mm3), right (73.9±15.1 vs. 91.2±12.4 mm3), and total (144.5±27.4 vs. 182.8±21.5 mm3) OB volumes were significantly lower in the RA group than in the control group (all p<0.05). Conclusion: Patients with RA may be under risk of decreased OB volumes and related impaired odor functions which might affect the quality of life and activities of daily living adversely.
