Correlation of serum albumin or zinc and S-SPT at time of enrollment. Abbreviation: S-SPT, simple 2-step swallowing provocation test. Shown p-values are the results of the test of no correlation with albumin, but significant correlation with zinc level. a Serum albumin level did not show a significant correlation with S-SPT time (Spearman’s rho = − 0.07; p = 0.60). b Serum zinc level showed a weak, but statistically significant, correlation with S-SPT time (Spearman’s rho = − 0.32; p = 0.0219)
