1 · What the graph read from it

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.

2 · The registry

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

objectiveAdolescents with anorexia nervosa (AN) are amenorrheic and have decreased bone mass accrual and low bone mineral density (BMD). The regulation of mesenchymal stem cell differentiation is an important factor governing bone formation. Preadipocyte factor 1 (Pref-1), an inhibitor of adipocyte and osteoblast differentiation, is elevated in states of oestrogen deficiency. In this study, we aim to (i) investigate effects of transdermal oestradiol on Pref-1 in adolescent girls with AN, and (ii) examine associations of changes in Pref-1 with changes in lumbar BMD and bone turnover markers.

designAdolescent girls with AN and normal-weight controls were studied cross-sectionally. Girls with AN were examined longitudinally in a double-blind study and received transdermal oestradiol (plus cyclic medroxyprogesterone) or placebo for 12 months. PATIENTS: Sixty-nine girls (44 with AN, 25 normal-weight controls) 13-18 years were studied at baseline; 22 AN girls were followed prospectively. MEASUREMENTS: Pref-1 levels, bone formation and resorption markers, and BMD.

resultsPref-1 levels decreased in girls with AN after treatment with transdermal oestradiol compared with placebo (-0·015 ± 0·016 vs 0·060±0·026 ng/ml, P = 0·01), although at baseline, levels did not differ in AN vs controls (0·246 ± 0·015 vs 0·267 ± 0·022 ng/ml). Changes in Pref-1 over 12 months correlated inversely with changes in lumbar BMD (r = -0·48, P = 0·02) and positively with changes in CTX (r = 0·73, P = 0·006).

conclusionsFor the first time, we show that Pref-1 is negatively regulated by oestradiol in adolescent girls with AN. Inhibition of Pref-1 may mediate the beneficial effects of transdermal oestradiol replacement on BMD in girls with AN.
