False-positive report probabilities under different scenarios

Prior probability	Odds ratio
	1.5	1.75	2
0.1	0.48	0.29	0.19
0.05	0.66	0.46	0.33
0.01	0.91	0.82	0.72
0.001	0.99	0.98	0.97

False-positive report probability values are presented for the association between the C+1354T single nucleotide polymorphism and systemic sclerosis in our population. Different ranges of values are reported in relation to the prior probability values and the power to detect different odds ratios for ⁴⁵²His/⁴⁵²Tyr individuals compared with ⁴⁵²His/452His subjects, with α = 0.009. Data in italics are reported noteworthy false-positive report probability values at the 0.5 level.
