not quite significantP = 0.081
Univariate linear regression analysis with P28 refractive error as the outcome variable and FDM (versus control) as the predictor variable, showed that if a P14 GP underwent 2 weeks of FDM, at P28 the refractive error was on average 1.85D more myopic than that in GPs undergoing physiological growth; this difference was not quite significant statistically ( P = 0.081, n = 70).
