After radioactive iodine treatment for an overactive thyroid, hormone levels don't just drop—they go up and down in predictable patterns before settling.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
