The agreement of the OMERACT grey-scale ultrasound scoring system for salivary glands and minor salivary gland biopsy results in a single-center cohort of patients with suspected Sjögren's disease.

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
objectiveSalivary gland ultrasound (SGUS) is a non-invasive tool for the evaluation of parenchymal changes related to primary Sjögrens disease (pSjD) with the potential to reduce the need for minor salivary gland biopsies when diagnosing patients with pSjD. The aim was to assess the agreement between SGUS findings and minor salivary gland biopsy results in patients suspected of pSjD.
methodsAll patients referred with a suspicion of pSjD and scheduled for a diagnostic minor salivary gland biopsy were included in the period 2017-2021. All underwent SGUS of the parotid and submandibular glands bilaterally, Schirmer's test, unstimulated salivary flow, and blood samples including autoantibody analysis. Changes in the four glands were scored 0-3 using a previously developed ultrasound atlas based on the OMERACT SGUS scoring system for pSjD. All biopsies were scored at the same pathology department and a focus score > 1 was indicative of pSjD.
resultsOf 103 patients included, 43 (42%) were diagnosed with pSjD and 40 (39%) fulfilled the 2016 ACR/EULAR classification criteria. Thirty-two (31%) had a positive minor salivary gland biopsy. The sensitivity of SGUS score ≥ 2 in at least 1 gland was 0.59 and the specificity 0.75. The positive predictive and negative predictive values were 0.51 and 0.80, respectively. The agreement slightly improved when combined with an abnormal salivary flow rate or abnormal Schirmer's test.
conclusionIn patients with suspected pSjD, we found good agreement between the OMERACT SGUS scoring system and minor salivary gland biopsy; however, SGUS cannot yet fully replace biopsy in the diagnostic setup of SjD.
