People have been "grinding my gears" by conflating carbohydrates with sugars. All sugars are carbohydrates, but not all carbohydrates are sugars. See Carbs Carbs Carbs. to find out about the five basic different types of carbohydrates.
Krauss et al has been "at it" again. In Separate effects of reduced carbohydrate intake and weight loss on atherogenic dyslipidemia, at the bottom of Table 1 is "carbohydrate, 50% simple and 50% complex". The carbohydrates consisted of half simple (probably fructose, as that has the worst effect on particle size) and half starches (probably maltodextrin, as it rapidly hydrolyses into glucose).
The effect of such a sugary diet is as follows:-
The percentage of pattern B (small, dense) LDL particles increases significantly in proportion to the percentage of Dietary "carbohydrate". The implication of this study (also A very-low-fat diet is not associated with improved lipoprotein profiles in men with a predominance of large, low-density lipoproteins ) is that high-carb, low-fat diets are atherogenic.
I call "Shenanigans".
A high sugar diet is atherogenic, but carbohydrates from potatoes, rice, sweet potatoes/yams & beans (if not overcooked), actual whole grains (i.e not flour) & whole fruits aren't.
