“…To illustrate this point, Malinovsky et al, 9 having reduced all their data into 4 bins only, calculated their weighted median values of ORs (Odds ratios), obtaining an OR of 1.35 with impressive credibility ( P < 0.0001) for their highest median radon concentration of 283 Bq/m 3 . In our recent paper (Reszczyńska et al) 22 we contested their work and their conclusions. Indeed, as pointed out by Scott, 18,47,48 if one considers the variability of natural background measurements, an OR value of 1.35 may not be realistic, which supports our view.…”
