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

backgroundLow birth weight (LBW) followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) plays an important role in the regulation of energy homeostasis, reducing food intake and body weight. We assessed whether GDF15 concentrations are raised by long-term metformin treatment in LBW/catch-up girls with precocious pubarche (PP, pubic hair <8 years), and whether they relate to changes in endocrine-metabolic variables, body composition, and abdominal fat partitioning.

methodsCirculating GDF15 was determined in 30 LBW/catch-up girls with PP randomly assigned to receive metformin for 4 years (n = 15; 425 mg/d for 2 years, then 850 mg/d for 2 years) or to remain untreated (n = 15). Endocrine-metabolic variables, body composition (by absorptiometry), and abdominal fat partitioning (by MRI) were assessed at the start and yearly during follow-up.

resultsCirculating GDF15 concentrations increased significantly in LBW-PP girls only after 3 and 4 years on metformin. GDF15 levels associated negatively with insulin, HOMA-IR, androgens, body fat, and visceral fat.

conclusionPrepubertal intervention with metformin reduces central adiposity and insulin resistance in girls with reduced prenatal growth. GDF15 could be among the mediators of such effects, especially over the long term. IMPACT: Low birth weight followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) is a peptide hormone that reduces food intake and lowers body weight; metformin is an exogenous GDF15 secretagogue. Serum GDF15 concentrations increase after 3 and 4 years on metformin and associate negatively with insulin, androgens, body fat, and visceral fat. Prepubertal intervention with metformin reduces central adiposity and insulin resistance in girls with low birth weight. GDF15 could mediate these effects, especially over the long term.
