Figure 1.

Selection of fallers and matched non-fallers.

Notes: The fall and DRMP databases were merged. DRMP patients screened post-fall and accidental fallers were excluded because the population characteristics differ. The left side of the figure shows the fallers who participated in the DRMP. The right side shows non-fallers who participated in the DRMP. Horizontal lines indicate groups that were excluded from analysis. Vertical lines indicate groups that were kept in the pool at each stage. The horizontal line between the bottom two squares represents the fallers in the DRMP and the non-fallers in the DRMP who were matched at a rate of 3:1.
