2. Fig. 1
Forest plot of study-specific estimates and summary OR estimates and 95% confidence intervals (95%CIs) for the association between (A) serum COMP and prevalence of knee OA (B) urinary CTX2 and prevalence of knee OA. fe summary = fixed effects summary statistic, re summary = random effects summary statistic. The inter-study heterogeneity I2 is shown along with the corresponding significance level for each fixed effects estimate. The statistical significance for fixed and random effects summary statistics is also shown.

Forest plot of study-specific estimates and fixed effects summary OR estimates and 95% confidence intervals (95%CIs) for the association between urinary CTXII and (A) prevalence of hand OA (B) prevalence of hip OA (C) radiographic severity of knee OA (D) progression of knee OA. fe summary = fixed effects summary statistic, re summary = random effects summary statistic. The inter-study heterogeneity I2 is shown along with the corresponding significance level for each fixed effects estimate. The statistical significance for fixed and random effects summary statistics is also shown.
