We utilized a 4\u2010point visual scale based on the level of contrast between palmar crease pigment and that of the surrounding skin. Score 0 indicated no difference, score 1 referred to a low difference, score 2 meant a moderate difference, and score 3 related to a high difference. Scores were subdivided based on the risk of PIH. Scores 0\u20101 are <jats:italic>low risk<\/jats:italic> and scores 2\u20103 are <jats:italic>high risk<\/jats:italic>.
