Fig. 5: Analysis of imprecision in pain score measurements across different days and APC Interventions.

The top left plot categorises pain scores into three imprecision categories—low, moderate, and high—based on the standard deviation (SD) and confidence intervals (CI). The top right plot shows the distribution of imprecision/variability across different days (Day 1, Day 2, Day 3, Day 7) for each intervention. The bottom plot displays the frequency of these imprecision categories by day.
