In a recently published article by Hong et al,1 there were two errors related to the acronym PASS:
1. In the last sentence on page 960 (...through the power analysis using Personal Alert Safety System (PASS) software), PASS is an acronym for Power Analysis and Sample Size.
2. In the second paragraph on page 964 (...cries for help, PASS alarms), PASS should be spelled out as Personal Alert Safety System alarms.
The authors apologize for the errors.
