What percentage of the implanted-only group reached the primary endpoint at 3 months?

The primary endpoint is a crucial measure in clinical studies that indicates the main outcome researchers are assessing. In this case, the statistic you're referring to shows that 93.3% of the implanted-only group achieved that primary outcome within a 3-month period. This significant percentage reflects the effectiveness and reliability of the treatment or intervention being studied in that specific group.

When looking at such results, achieving over 90% demonstrates a strong positive response among participants, suggesting that the implant was successful in a majority of cases. This level of success can also imply that the treatment is worth considering for broader use, given the high percentage of individuals who benefited from it.

Other options provide lower percentages which do not accurately represent the data, leading to the conclusion that 93.3% is the most reliable and precise figure for this group at the 3-month mark. The strong outcome further validates the effectiveness of the intervention being assessed in the study.
