Table 6 Multivariable analysis of the Lebanese Medication Adherence Scale (LMAS)

Model 1: Linear regression taking into account the socioeconomic level as independent variables
Factor	Unstandardized beta	Standardized beta	95% CI	P-value
Married vs. non-married*	− 3.978	− 0.362	− 7.322; − 0.635	0.021
Household crowding index	2.561	0.304	0.359; 4.763	0.023

Model 2: Linear regression taking into account the current medication shortage as independent variables
Factor	Unstandardized beta	Standardized beta	95% CI	P-value

Harmful Impact of Medication Shortage scale	0.498	0.716	0.362; 0.634	< 0.001

Model 3: Linear regression taking into account current medication shortage and economic status as independent variables
Factor	Unstandardized beta	Standardized beta	95% CI	P-value
