Developing a Modified Low-Density Lipoprotein (M-LDL-C) Friedewald’s Equation as a Substitute for Direct LDL-C Measure in a Ghanaian Population: A Comparative Study

Table 2

Mean percentage difference between D-LDL-C and calculated LDL-C.

	∆ F-LDL-C ()	∆ N-LDL-C ()	∆A-LDL ()	∆M-LDL-C ()
Mean	12.39	11.74	23.54	21.33
SD	27.34	29.25	30.45	28.43
1st Quartile	4.33	5.07	1.39	3.63
Median	13.79	13.51	23.84	23.8
3rd Quartile	29.63	28.55	44.81	39.11

SD: standard deviation; ΔA-LDL-C: mean percentage difference for Friedwald’s formula; ΔA-LDL-C: mean percentage difference for Martin formula; ΔA-LDL-C: mean percentage difference for Anandaraja’s formula; ΔA-LDL-C: mean percentage difference for modified formula. Mean percentage difference was calculated as [(calculated LDL-C)-(D-LDL-C)] ∕D-LDL-C100].
