Quote: But, during the course of the study, regular cycling cut the risk of death from any cause by 41%, the incidence of cancer by 45% and heart disease by 46%.
However, the effect was still there even after adjusting the statistics to remove the effects of other potential explanations like smoking, diet or how heavy people are. Saya kira bersepeda ke kantor (atau sport lain) akan mengurangi resiko terjadinya kanker sampai 45%, angkanya terlalu tinggi. Apalagi setelah di koreksi secara statistik dgn. factor merokok, diet, gemuk/berat badan (confounding factors). Kalau mengurangi penyakit jantung sampai 46%, lebih bisa di mengerti.
