    Snippet: All statistical analyses were performed using SPSS Statistics 22.0. Spearman's rank correlation coefficient was calculated to study trends over time. The statistical significance of differences between proportions was compared with Chi-squared test. A P-value of < 0.05 was considered as statistically significant. To determine if the same temporal changes occurred in SUC publications, we repeated the search process in the WANFANG, VIP and CNKI dat.....
    Document: All statistical analyses were performed using SPSS Statistics 22.0. Spearman's rank correlation coefficient was calculated to study trends over time. The statistical significance of differences between proportions was compared with Chi-squared test. A P-value of < 0.05 was considered as statistically significant. To determine if the same temporal changes occurred in SUC publications, we repeated the search process in the WANFANG, VIP and CNKI databases with the search terms "severe ulcerative colitis" in the Article Title or Keywords. About 510 papers were retrieved from these three databases when the publication year was limited to the most recent 15 years
