Additional file 1: Supplemental Figure 1. Recruitment and enrollment of study participants in Xiangya Osteoarthritis Study (XO Study). Supplemental Figure 2. Longitudinal ultrasonographic scan of suprapatellar recess (B mode). SH, synovial hypertrophy; E, joint effusion. Supplemental Figure 3. Longitudinal ultrasonographic scan of suprapatellar recess (Power Doppler mode). Power Doppler signal (PDS) at synovial membrane was scored using a semi-quantitative grading system, from 0 to 3 (0=absent, 1=mild, 2=moderate, 3=marked or severe). (A) grade 0, (B) grade 1, (C) grade 2. We did not detected grade 3 PDS in knee joints of participants of our study. Supplemental Figure 4. Bilateral weight-bearing posterior-anterior tibio-femoral radiographs, assessed according to Kellgren and Lawrence (KL) criteria: (A) grade 0, (B) grade 1, (C) grade 2, (D) grade 3 and (E) grade 4. Supplemental Figure 5. Skyline views of patellofemoral radiographs, assessed according to Kellgren and Lawrence (KL) criteria: (A) grade 0, (B) grade 1, (C) grade 2, (D) grade 3 and (E) grade 4. Supplemental Table 1. The intra- and inter-rater reliability for ultrasound-detected synovial abnormalities and Kellgren-Lawrence grade of knee radiography. Supplemental Table 2. Prevalence of knee synovial abnormalities on ultrasound among middle-aged and elderly persons, according to age group and sex. Supplemental Table 3. Association of knee synovial abnormalities on ultrasound and knee pain. Supplemental Table 4. Association of knee synovial abnormalities on ultrasound and knee pain among people with two knees discordant for knee pain. Supplemental Table 5. Association of knee synovial abnormalities on ultrasound and knee radiographic osteoarthritis. Supplemental Table 6. Association of knee pain stratified by knee synovial abnormalities on ultrasound and radiographic osteoarthritis status among people with two knees discordant for knee pain.
