Abbreviations: MRSS Modified Rodnan skin score, EScSG European Scleroderma Study Group, PAH Pulmonary arterial hypertension, ILD Interstitial lung disease, GAVE Gastric antral vascular ectasia, eGFR Estimated glomerular filtration rate, CRP C-reactive protein, ESR Erythrocyte sedimentation rate, CK Creatinine kinase, FVC Forced vital capacity, DLCO Diffusing capacity of the lung for carbon monoxide corrected for haemoglobin
-
aEver from disease onset to most recent visit
-
bPericardial effusion defined by echocardiography
-
cPAH defined by right heart catheterization with a mean pulmonary artery pressure ≥25 mmHg and a pulmonary arterial wedge pressure ≤15 mmHg
-
dPulmonary fibrosis defined by chest high-resolution computed tomography
-
eGastrointestinal symptoms defined as the presence of any of reflux, dysphagia, post-prandial bloating, vomiting, constipation, diarrhoea or anal incontinence as defined in text
-
fRenal crisis defined as the presence of at least two of the following: new-onset hypertension, rising creatinine or microangiopathic haemolytic anaemia
-
gMyositis defined as either definite (biopsy), suspected (CK or electromyogram) or possible (magnetic resonance imaging scan)
-
hAnaemia defined as haemoglobin level <135 g/L in males and <120 g/L in females
-
iCalculated without hypocomplementaemia. Final scores range from 0 to 9, with higher scores indicating higher disease activity
-
jIncludes leflunomide, methotrexate, azathioprine, penicillamine, hydroxychloroquine, mycophenolate, cyclophosphamide and calcineurin inhibitors
-
kIncludes tumour necrosis factor alpha inhibitors, tocilizumab, abatacept, anti-CD20 antibodies and other B-cell modulators
-
lHighest score ever recorded over the study period
-
mScores range from 0 to 10, with higher scores being indicative of worse overall health
-
nScores range from 0 to 10, with higher scores being indicative of higher disease activity or damage
