The substantial limitation of these datasets is that they are based on correlation, not causation, and have and some difficulty reading the scale. While they represent the correlation between vaccine coverage and measles cases, they do not establish a direct causal relationship. Most datasets cover a substantial time period, providing a more concise trend analysis and interpretation that matches an adequate research question, effectively shows the relationship between vaccine coverage and measles incidence.
The main limitation of these datasets is that they are based on correlation rather than causation and have some difficulty in reading the scale. While they depict the correlation between vaccine coverage and measles cases, they do not establish a direct causal relationship. However, most datasets cover a significant time period, allowing for a concise trend analysis and interpretation that can effectively demonstrate the relationship between vaccine coverage and measles incidence.
Here is the corrected grammar:
