Table 1 presents the sociodemographic and health history characteristics derived from the patients' profile and background, encompassing variables such as sex, date of birth, education level, monthly income, and respective socioeconomic status following the criteria of the Chilean Association of Market Researchers [36]. Regarding clinical details for osteoarthritis (OA) participants, the recorded medical information included the specific diagnosis, severity level as determined by the Kellgren-Lawrence Scale, and whether the condition affected joints unilaterally or bilaterally. \begin{table}

Table 1: Sociodemographic and health history characteristics. First Research Question: What Is the Relationship between Health Antecedents (Such as Disease Severity, Bilaterality, Type of OA, and Medication Use) and Levels of Functionality in Chilean Individuals with OA? Table 2 presents the results of [PERSON]'s correlation analysis. Significant associations were found between higher levels of functionality problems, as measured by the Lequesne Index, and greater severity of osteoarthritis (OA) according to the Kellgren-Lawrence Scale (\(p<0.001\)). Additionally, there were strong correlations with higher pain levels assessed using the Visual Analog Scale (VAS) (\(p<0.001\)) and with physical activity levels evaluated by the IPAQ-SF (\(p=0.030\)). Likewise, greater OA severity was consistently linked to higher functionality problems (\(p<0.001\)). Moreover, the findings of this research indicate that individuals who suffer from bilateral OA present higher levels of functionality problems (\(p=0.030\)) and higher levels of pain (\(p=0.049\)) than individuals with unilateral OA. Likewise, individuals with higher levels of pain used medication (\(p=0.011\)). Finally, higher levels of severity were present in those who presented both knee and hip OA, in contrast with individuals who suffered \begin{table}
