Maximum Phonation Time in People with Obesity Not Submitted or Submitted to Bariatric Surgery

Table 4

Spearman correlation coefficient (rho) of maximum phonation time (MPT) and S/Z ratio with weight, height, body mass index (BMI), neck circumference (NC), forced expiratory volume in one second (FEV₁), forced vital capacity (FVC), and the relation FEV₁/FVC measured in nonoperated people with obesity (Group A, n = 52).
