Association rule analysis between lncRNA HOTAIR and laboratory indicators in OA patients

Items (LHS ⇒ RHS)	Support (%)	Confidence (%)	Lift	p value
{lncRNA HOTAIR↑}⇒{Hospitalization days↓}	63.636	76.087	1.02	< 0.01
{lncRNA HOTAIR↑}⇒{sex (female)}	56.364	67.391	1.05	< 0.01
{lncRNA HOTAIR↑}⇒{SDS↑}	63.636	76.087	1.03	< 0.01
{lncRNA HOTAIR↑}⇒{ESR↑}	61.818	73.913	1.03	< 0.01
{lncRNA HOTAIR↑}⇒{VAS↑}	67.273	80.435	1.01	< 0.01
{lncRNA HOTAIR↑}⇒{LDL-C↑}	27.273	32.609	1.02	< 0.01

For correlations, Aprior module analysis was used. The minimal level of support was set at 20%, while the minimum level of confidence was set at 30%. When the degree of the lift was set to greater than 1, it was deemed important
