Question:

What test can be used to compare the variance of ln (ERG amplitude) between patients with dominant vs. recessive RP? 


Ophthalmology

A study compared mean electroretinogram (ERG) amplitude of patients with different genetic types of retinitis pigmentosa (RP), a genetic eye disease that often results in blindness. The results shown in Table 8.24 were obtained for ln (ERG amplitude) among patients 18€“29 years of age.

Table 8.24: Comparison of mean ln (ERG amplitude) by genetic type among patients with RP

 Genetic type Mean + sd in Dominant 0.85 + 0.18 0.38 + 0.21 -0.09 ± 0.21 62 35 Recessive X-linked 28
