Patient disposition. *Patients were excluded if: a) DXR-BMD could not be analysed due to technical problems (insufficient exposure of x-rays, insufficient positioning of hands) or disease-related factors (prostheses, severe bone damage); or b) DXR-BMD change (i.e. hand bone loss) could not be calculated due to change in acquisition modality between original x-rays (e.g. x-ray film at baseline and digital image at follow-up) or large change in digital image post-processing between x-rays (edge enhancement and change in x-ray resolution). csDMARD Conventional synthetic disease-modifying anti-rheumatic drug, DXR-BMD Bone mineral density estimated by digital x-ray radiogrammetry, TNFI Tumour necrosis factor alpha inhibitors
