Prevalence of Spondyloarthritis Among Patients Who Underwent Lumbar Disc Herniation Surgery.
Article in Archives of rheumatology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis study aims to estimate the prevalence of spondyloarthritis (SpA) among patients who had been surgically treated for lumbar disc herniation (LDH), according to the modified New York (mNY) criteria for the diagnosis of ankylosing spondylitis and Amor, the European Spondyloarthropathy Study Group (ESSG), the Assessment of Spondyloarthritis International Society (ASAS) classification criteria for SpA. PATIENTS AND
methodsThe study included 321 patients (142 males, 179 females; mean age 49±10.8 years; range, 18 to 79 years) who underwent LDH surgery between April 2008 and May 2012 in the neurosurgery clinic of our hospital. Patients were contacted by phone on at least two attempts. Totally, 123 patients accepted to come to the outpatient clinic, while the remaining 198 agreed to be interviewed on the phone. Patients who agreed to come to the outpatient rheumatology clinic underwent clinical examination, and pelvic X-ray and magnetic resonance imaging (MRI) scan of the sacroiliac joints when indicated.
resultsInflammatory back pain was diagnosed in 108 patients (34%) and 40 patients (13%) according to Calin criteria and the ASAS criteria, respectively. Prevalence of SpA among all patients was estimated as 17.7% according to the ESSG criteria, and 8.7% according to Amor criteria. Five of the 308 pelvic radiographs had definite radiographic sacroiliitis as required by the mNY criteria. Four patients had a characteristic pattern of bone marrow edema on MRI examination in accordance with the ASAS definitions. The overall prevalence of sacroiliitis (MRI sacroiliitis+X-ray sacroiliitis) among the patients who came to the clinic was 7.3% ([4+5]/123).
conclusionThe relatively increased prevalence of SpA among patients who underwent LDH surgery indicates the necessity of increasing awareness on the new concept of axial SpA for specialists treating patients with low back pain.
