Trial report in European journal of endocrinology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05826210 (Effect of Sarcopenic Obesity on Weight Loss Outcomes and Quality of Life After Laparoscopic Sleeve Gastrectomy), which is not on this map. Cited by 31 papers, 1 of them a synthesis that pooled it.

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.

Abstract

objectiveShort-term energy deprivation reduces leptin concentrations and alters the levels of circulating hormones of the hypothalamic-pituitary-peripheral axis in lean subjects. Whether the reduction in leptin concentration during long-term weight loss in obese individuals is linked to the same neuroendocrine changes seen in lean, leptin-sensitive subjects remains to be fully clarified.

methodsIn this study, 24 overweight and obese adults (16 women and eight men; body mass index (BMI): 27.5-38.0 kg/m(2)) were prescribed a hypocaloric diet (-500 kcal/day) and were randomized to receive recombinant methionyl leptin (n=18, metreleptin, 10 mg/day self-injected s.c.) or placebo (n=6, same volume and time as metreleptin) for 6 months.

resultsMetreleptin administration did not affect weight loss beyond that induced by hypocaloric diet alone (P for interaction=0.341) but increased the serum concentrations of total leptin by six- to eight-fold (P<0.001) and led to the generation of anti-leptin antibodies. Despite free leptin concentration (P for interaction=0.041) increasing from 9±1 ng/ml at baseline to 43±15 and 36±12 ng/ml at 3 and 6 months, respectively, changes in circulating hormones of the thyroid and IGF axes at 3 and 6 months were not significantly different in the placebo- and metreleptin-treated groups.

conclusionsLeptin does not likely mediate changes in neuroendocrine function in response to weight loss induced by a mild hypocaloric diet in overweight and obese subjects.
