Associations between fructose levels and the degree of hypoxemia. (A): Association between baseline plasma fructose levels and lowest SpO₂ levels during sleep at diagnosis. (B): Associations between changes in plasma fructose levels and baseline plasma fructose levels (upper left), lowest SpO₂ levels during sleep at diagnosis (upper right), changes in lowest SpO₂ levels during sleep (lower left) and changes in AHI (lower right). Each dot indicates one patient. Spearman’s rank correlation test was used.
