Comments on Frey's "Data analysis reveals significant microwave-induced eye damage in humans".

Abstract

Frey's critique and analysis of the Appleton-McCrossan and Appleton et al studies were examined. Frey is criticized for: ignoring pooling problems in his chi-square test; not analyzing the opacity data in Appleton et al; not analyzing the data on vacuoles and posterior subcapsular iridescence in Appleton and McCrossan and Appleton et al; and failing to do log-linear analysis which is appropriate for the design in the two studies. Application of log-linear tests to the opacity data in both studies leads to the conclusion that subject age was significantly associated with the occurrence of opacities, but, contrary to Frey's conclusion, microwave radiation was not.

Main findings

The authors re-examined Frey’s critique/analysis of two prior studies and report that log-linear tests of opacity data indicated subject age was significantly associated with opacities, whereas microwave radiation was not significantly associated (contrary to Frey’s conclusion).

Outcomes measured

• eye damage
• lens opacities
• vacuoles
• posterior subcapsular iridescence

Limitations

• This is a commentary/re-analysis of previously published studies rather than new primary data.
• Details of exposure parameters (frequency, SAR, duration) are not provided in the abstract.
• Sample size and population characteristics of the underlying studies are not reported in the abstract.
