-    - "Test case": name of CSIT test case, naming convention here
-      `CSIT/csit-test-naming <https://wiki.fd.io/view/CSIT/csit-test-naming>`_
-    - "Thput trend [Mpps]": last value of trend over rolling window.
-    - "Anomaly value [Mpps]": in precedence - i) highest outlier if 3
-      consecutive outliers, ii) highest regression if regressions detected,
-      iii) highest progression if progressions detected, iv) nil if normal i.e.
-      within trend.
-    - "Anomaly vs. Trend [%]": anomaly value vs. trend value.
-    - "Classification": outlier, regression, progression, normal - observed
-      over a rolling window.
-    - "# Outliers": number of outliers detected.

+    - **Trend Compliance** : calculated based on detected anomalies over a

+      consecutive outliers, ii) **regression** if any regressions, iii)
+      **progression** if any progressions, iv) **normal** if data compliant
