Effects of antibody to receptor activator of nuclear factor κ-B ligand on inflammation and cartilage degradation in collagen antibody-induced arthritis in mice

Table 1 Frequency of swelling in limb pads

Group	Fore limb		Hind limb		Total
Group	Left	Right	Left	Right	Total
RA-/Ab-	0/6	0/6	0/6	0/6	0/6
RA-/Ab+	0/6	0/6	0/6	0/6	0/6
RA+/Ab-	1/6	5/6	1/6	0/6	5/6
RA+/Ab+	4/5	3/5	1/5	1/5	4/5

Development of inflammation in the 4 limbs was evaluated daily by measuring the thickness of each footpad (Additional file 1: Figure S1). Occurrence of swelling in the limbs until day 14 is shown as a fraction, with the numerator and denominator representing the number of mice with swollen limb(s) and total number of mice in the group, respectively.
