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

introductionPeroxisome proliferator-activated receptor (PPAR) subfamily play an important role in chondrogenesis. Previous study has reported that mixture of GW0742 (PPAR-δ agonist), hyaluronic acid (HA) and mesenchymal stem cells (MSCs) enhance chondrogenesis. The purpose of this study is to compare with efficacies of commercially available HA and demonstrate correlation of PPAR-γ and PPAR-δ.

methodsIn this experimental study, MSCs were cultured with chondrogenic media and clinical HA gels (Euflexxa®, Synvisc®, Orthovisc® and Supartz®) using micormass culture method. Expression of type Ⅰ, Ⅱ collagen and matrix metalloprotease-13 (MMP-13) was measured by immunoblotting. MSCs were cultured with chondrogenic media and/or HA and/or GW0742 and/or rosiglitazone (PPAR-γ agonist) and/or human osteoarthritis synovial fluid. Immunoblotting was used to measure expression of type Ⅱ collagen and PPAR-γ. To identify the effective dose for chondrogenesis and adipogenesis, either 0.1, 1, 5 or 10 μM of rosiglitazone was added to MSCs in chondrogenic media or adipogenic media.

resultsClinical HA gels inhibited expression of type Ⅰ collagen and enhanced the expression of MMP-13. Type Ⅱ collagen expression was significantly elevated in all treatment groups except Supartz®. GW0742 decreased the expression of PPAR-γ with/without inflammation condition. Rosiglitazone enhanced adipogenesis in a dose-dependent manner and enhanced the expression of type Ⅱ collagen under inflammation condition. Otherwise, the expression of type Ⅱ collagen and formation of chondrocyte spheroids showed a dose-dependent manner with a peak at 1 μM of rosiglitazone.

conclusionsPPAR-γ has a considerable anti-inflammatory effect and a strong pro-adipogenic effect, which inhibits the chondrogenic effect. PPAR-γ is related with PPAR-δ and shows a chondrogenic effect at lower concentrations. And clinical HA gels shows various efficacy of chondrogenesis. This study suggested that PPAR-γ and PPAR-δ are key regulatory factors of chondrogenesis.
