Nailfold capillaroscopy image assessing tool. Scoring scale developed by the authors, based on EULAR (European League Against Rheumatism) Guidelines (2008) [17]. Each nailfold image was divided into 4 consecutive 1 mm fields, which were analysed for nailfold abnormalities including: giant capillaries, capillary density, neoangiogenic capillaries, haemorrhages, morphology, presence of microaneurysms, avascular areas and the dominant capillary shape. The score was the average of each assessors abnormality count, for each nailfold.
