Serum leptin levels in acromegalic patients before and during somatostatin analogs therapy.
Trial report in Journal of endocrinological investigation, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
GH excess is characterized by alterations of body composition such as decreased body fat mass; however, scant data are present regarding its effect on serum leptin levels. To better elucidate this topic, leptin secretion was studied in 20 acromegalic patients, before and after 6 months of treatment with somatostatin analogs (SR-lanreotide 30 mg and octreotide LAR). Basal GH, IGF-I, insulin, blood glucose and lipid levels were measured and the area under the curve (AUC) for insulin and glucose and oral glucose insulin sensitivity (OGIS) during oral glucose tolerance test (OGTT) were calculated. After 6 months of somatostatin analogs therapy, a significant reduction in GH and IGF-I plasma levels was observed (p<0.0005, both) with a significant increase of leptin levels (7.4+/-1.3 vs 13.2+/-1.6 ng/ml; p<0.05). Interestingly, the typical correlation of leptin with body mass index (BMI) was not present in active acromegaly, whereas it was restored after somatostatin analogs treatment; moreover, the gender difference in leptin secretion between men and women was preserved in active and controlled acromegaly. In conclusion, the gender-based leptin differences are preserved and leptin secretion/BMI ratio is normalized in acromegalic patients after somatostatin analogs therapy.
