Adolescent polycystic ovary syndrome without obesity: HOTAIR rs1443512 genotype relates to fat mass and to the redistribution of fat mass on low-dose pioglitazone.

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
introductionAdolescent polycystic ovary syndrome (PCOS) is characterized by androgen excess and oligo-amenorrhea, and often results from ectopic lipid storage due to a mismatch between early adipogenesis and later lipogenesis. Endogenous HOX transcript antisense RNA (HOTAIR) and exogenous pioglitazone are enhancers of subcutaneous adipogenesis, particularly in the gluteofemoral region. The A allele of HOTAIR rs1443512 is an equivalent of a natural knock-down and is, thus, a candidate to influence the distribution of fat mass, and also the redistribution of fat mass by pioglitazone in adolescent PCOS-without-obesity. SUBJECTS AND
methodsWe performed two post hoc analyses by HOTAIR rs1443512 genotype. In the first, we analyzed the pooled pre-treatment data (auxology; endocrinology; body composition by dual X-ray absorptiometry; abdominal fat distribution by magnetic resonance imaging) of 65 adolescent girls with PCOS-without-obesity in three reported studies (ISRCTN45546616; ISRCTN29234515; ISRCTN11062950). In the second, we analyzed the results of 24 adolescent girls with PCOS-without-obesity, who received pioglitazone (7.5 mg/d for 1 year) as part of a randomized combination treatment (with spironolactone and metformin) in two reported studies (ISRCTN29234515; ISRCTN11062950). All data had been obtained in a blinded-to-genotype way.
resultsThe pre-treatment data disclosed that the girls-with-A-allele of HOTAIR rs1443512 had developed PCOS with a lower BMI (22.3 ± 2.3 kg/m
conclusionThe present findings suggest that the HOTAIR rs1443512 genotype influences not only the distribution of fat mass in adolescent girls with PCOS-without-obesity but also the redistribution of fat mass during prolonged treatment with low-dose pioglitazone.
