Fig. 5From: A systematic review of the incidence, risk factors and prognosis of acute exacerbation of systemic autoimmune disease-associated interstitial lung diseaseForrest plot of the result of univariate analysis for a percentage of predicted forced vital capacity (%FVC) as a prognostic factor. The result of univariate analysis in three studies was pooled for meta-analysis. There was no significant difference in %FVC between decedents and survivors of acute exacerbation (AE) of systemic autoimmune disease-associated interstitial lung disease (ILD) with a mean difference (MD) of − 5.95 (95% confidence interval: − 13.90 to 1.99, p = 0.14). There was mild and statistically non-significant heterogeneity (chi2 = 2.22, p = 0.33, I2 = 10%)Back to article page
