Following publication of the original article [1], the authors reported the unit errors found in the Abstract section, Introduction section, and Results section.
In results of abstracts section, the following sentence contains a unit error:
After adjusting for basic socio-demographic factors, a 10 mg/m3 increase in 3-year exposure to PM10 was significantly associated with a decrease in the DSST score by −0.05 (95% confidence interval [CI]: −0.11, 0) and an increase in the TMT-B score by 0.05 (95% CI: 0.01, 0.10).
The correct sentence should be:
After adjusting for basic socio-demographic factors, a 10 µg/m3 increase in 3-year exposure to PM10 was significantly associated with a decrease in the DSST score by −0.05 (95% confidence interval [CI]: −0.11, 0) and an increase in the TMT-B score by 0.05 (95% CI: 0.01, 0.10).
In the Results section, the following sentence contains unit errors:
The mean (SD) 1-year and 3-year annual concentrations for PM2.5 were 36.35 ± 6.25 mg/m3 and 39.45 ± 7.11 mg/m3, respectively, while the corresponding values for PM10 were 75.40 ± 11.93 mg/m3 and 74.07 ± 18.86 mg/m3.
The correct sentence should be:
The mean (SD) 1-year and 3-year annual concentrations for PM2.5 were 36.35 ± 6.25 µg/m3 and 39.45 ± 7.11 µg/m3, respectively, while the corresponding values for PM10 were 75.40 ± 11.93 µg/m3 and 74.07 ± 18.86 µg/m3.
Similarly, in the results section, the sentence contains a unit error:
A 10 mg/m³ increase in PM10 was significantly associated with a decrease in the DSST score by −0.05 (95% CI: −0.11, 0) and an increase in the TMT-B score by 0.05 (95% CI: 0.01, 0.1).
The correct sentence should be:
A 10 µg/m³ increase in PM10 was significantly associated with a decrease in the DSST score by −0.05 (95% CI: −0.11, 0) and an increase in the TMT-B score by 0.05 (95% CI: 0.01, 0.1).
In introduction section, the following sentence contains a unit errors:
A study from the United States that included 780 old adults based their assessment of cognitive function primarily on memory and reported that cognitive function declined 53% per each 10 mg/m3 increment of PM2.5.
The correct sentence should be:
A study from the United States that included 780 old adults based their assessment of cognitive function primarily on memory and reported that cognitive function declined 53% per each 10 µg/m3 increment of PM2.5.
In introduction section, the following sentence contains a unit errors:
A system review that included four studies from Canada, the UK, the US, and Taiwan reported that every 10 mg/m3 increase in PM2.5 was associated with Alzheimer’s disease (pooled HR: 4.82 95%CI: 2.28, 7.36) and dementia (pooled HR: 3.26, 95%CI: 1.20, 5.31).
The correct sentence should be:
A system review that included four studies from Canada, the UK, the US, and Taiwan reported that every 10 µg/m3 increase in PM2.5 was associated with Alzheimer’s disease (pooled HR: 4.82 95%CI: 2.28, 7.36) and dementia (pooled HR: 3.26, 95%CI: 1.20, 5.31).
