3.2.1. Exploratory Multiple Correlation Analysis

Exploratory multiple correlation analysis revealed an association between BMI and selective and sustained attention (d2 Attention test [d2\_TR, d2\_CON and d2\_TOT]; *R* = 0.46, *p* = 0.009) and information processing speed (TMT Conditions 2 and 3 and 5DT Conditions 1–4; *R* = 0.52, *p* = 0.021). In addition, the different pain indices (MPQ) were associated with visuospatial memory (ROCF copying and memory conditions; *R* = 0.48, *p* = 0.001 for sensorial pain; *R* = 0.46, *p* = 0.003 for affective pain; and *R* = 0.49, *p* = 0.001 for miscellaneous pain). No other associations were observed in the multiple correlation analysis.
