Linkage disequilibrium (LD) in LEPR polymorphisms between obese and control groups. The pairwise LD plot was created by Haploview 4.2. Within each diamond the pairwise standardized coefficient of LD (D’) or the correlation coefficient (r²) is presented in percentage. Standard color coding was used for the Haploview LD plots with the confidence bounds color scheme, for the D’ plot, numbers are representative LD and the logarithm of the odds are in color: white = strong evidence of recombination; light grey = uninformative; dark grey = strong evidence of LD; for r² LD plots white (r² = 0), shades of grey (0 < r² < 1), black (r² = 1). A marker pair is said to show moderate or usable LD if |D’| is between 0.33 and 0.5, and strong LD if |D’| is 0.5 or above (i.e. at least half the maximum value)
