Sickle cell trait and longitudinal change in Word List Learning (WLL) and Delayed Recall (WLR).
Blue lines represent those with sickle cell trait and black lines those without sickle cell trait. Models were adjusted for age, sex, education, income, region, eGFR, systolic blood pressure, diabetes, alcohol use, smoking status, exercise frequency, coronary heart disease, left ventricular hypertrophy, atrial fibrillation, hyperlipidaemia, statin use, and hypertension. Note, y axis starts with a score of 5 words for ease of displaying the data. Numbers below the figure show the sample sizes.
Baseline SD of Scores: WLL (SCT) = 5.0; WLL (No SCT) = 5.0; WLR (SCT) = 2.3; WLR (No SCT) = 2.2. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
