A pilot prospective study of arterial stiffness during weight restoration in adolescents with anorexia nervosa.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeCarotid-femoral pulse wave velocity (cfPWV), an index of arterial stiffness, is one of the earliest indicators of cardiovascular risk. Studies of adolescents with anorexia nervosa have demonstrated increased arterial stiffness compared to healthy controls. Little information is available on the effect of weight restoration on arterial stiffness in adolescents with anorexia nervosa.
methodsThis pilot longitudinal study examined changes in arterial stiffness during weight restoration in adolescent females admitted to an inpatient eating disorder unit. Female adolescents aged 15-19 years with a diagnosis of anorexia nervosa and a body mass index (BMI) < 85% of median BMI for age and sex, were recruited from consecutive eating disorder admissions at Westmead Hospital, Australia. Weekly measurements of cfPWV were performed for up to 4 consecutive weeks.
results12 participants were included, with an average follow-up of 3.2 ± 1.1 weeks. Using mixed-effects models, we observed a significant increase in BMI (95% CI 0.60, 0.80; p < 0.01) along with a modest but statistically significant decrease in cfPWV. The rate of change in cfPWV observed was - 0.2 m/s per week (95% CI - 0.37, - 0.03; p = 0.03). Mean arterial pressure (MAP) was significantly associated with cfPWV (p < 0.01). There was a borderline association between cfPWV and BMI (p = 0.05).
conclusionsOur findings suggest a possible reduction in arterial stiffness with weight restoration, although results must be interpreted with caution due to the small sample. Nevertheless, serial measurements of cfPWV in this population are feasible, supporting the need for larger longitudinal studies in this population. LEVEL OF EVIDENCE: Level III.
