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
backgroundThiazolidinediones (TZDs) improves insulin sensitivity by activating the peroxisome proliferator-activated receptor γ (PPAR-g). We aimed to study any association between variation in bone biochemical markers and single nucleotide polymorphism (SNP) in PPAR-γ (Pro12Ala) and investigate if these genetic variants affect bone turnover markers in Iranian diabetic population before and after treatment with pioglitazone. MATERIALS AND
methodsA total of 101 patients (type 2 diabetic (T2D) were treated for 12 weeks with pioglitazone (15 mg/day). Bone Biological markers, osteocalcin, and C-terminal telopeptide of type 1 collagen (CTx) were measured before and after pioglitazone therapy. We genotyped 128 nondiabetic controls and 101 T2D patients as well. Pro12Ala polymorphism in PPAR-γ was done by real-time polymerase chain reaction (RT-PCR) using TaqMan assay.
resultsThere were statistically significant differences in allele frequencies of Pro12Ala while comparing the controls with T2D subjects. Ala frequency was 7 vs 3%, P = 0.036 and genotypic frequency of Pro/Ala was 5.94 vs 14.06%, P = 0.04. After treatment, the homeostasis model of assessment of insulin resistance (HOMA-IR) as a maker of insulin resistance was significantly decreased (P < 0.001). In respect of bone turnover markers, CTx values decreased and osteocalcin significantly increased. (P < 0.001).
conclusionOur findings did not reveal a significant association between this polymorphism and bone turnover markers after pioglitazone treatment. The reduced insulin resistance might be the reason that CTx values decreased and osteocalcin increased significantly after short-term pioglitazone treatment. These findings suggest the need for further studies on the possible role of insulin in regulation of bone metabolism.
