| Abstract |
To identify independent risk factors that differentiate gout from pseudogout in patients that present with crystal-induced acute arthritis. This cross-sectional study was conducted at Siriraj Hospital (Bangkok, Thailand) during the 25 May 2014-28 November 2014 study period. Patients who presented with crystal-induced acute arthritis were eligible for inclusion. Diagnosis of gout or pseudogout was made by microscopic visualization and analysis of crystals in synovial fluid. Patients with other causes of acute arthritis were excluded. Patients diagnosed with gout were compared with patients diagnosed with pseudogout and factors with a p value less than 0.05 were included in logistic regression analysis. A total of 103 patients were included. Gout and pseudogout were established in 59 (56.7%) and 44 (42.3%) patients, respectively. Gout patients were younger than pseudogout patients (66.9 ± 14.5 vs. 78.9 ± 12.0 years; p = 0.0001); had higher BMI (22.9 ± 2.5 vs. 21.0 ± 2.5 kg/m2; p = 0.001); had history of recurrent arthritis (91.5 vs. 9.1%; p = 0.001); had higher prevalence of below-knee arthritis (66.1 vs. 31.8%; p = 0.001); had less periarticular soft tissue swelling (57.6 vs. 81.8%; p = 0.01); and had hyperuricemia (8.0 ± 2.5 vs. 5.6 ± 2.7; p = 0.001). In adjusted multivariate analysis, hyperuricemia during acute arthritis/gouty attack characterized gout (OR 2.08, 95% CI 1.2-3.6), while monoarticular attack (OR 4.12, 95% CI 1.3-13.0) and periarticular soft tissue swelling (OR 4.03, 95% CI 1.1-14.9) were indications for pseudogout. The independent risk factors were found to differentiate gout from pseudogout: Gout: hyperuricemia during gouty attack; Pseudogout: monoarticular attack and periarticular soft tissue swelling. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 September 2018.
All research outputs
#15,490,822
of 23,020,670 outputs
Outputs from Rheumatology International
#1,561
of 2,204 outputs
Outputs of similar age
#266,827
of 440,019 outputs
Outputs of similar age from Rheumatology International
#21
of 40 outputs
Altmetric has tracked 23,020,670 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,204 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 440,019 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 40 others from the same source and published within six weeks on either side of this one. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
