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

introduction and hypothesisThe use of permanent synthetic meshes to improve the outcome of pelvic organ prolapse (POP) repair causes frequent and serious complications. The use of the synthetic, biodegradable scaffold methoxypolyethyleneglycol-polylactic-co-glycolic acid (MPEG-PLGA) seeded with autologous muscle fiber fragments (MFF), as an adjunct to native tissue POP repair, is a potential new alternative.

methodsA rat abdominal wall model of native repair was used with six animals in each of three groups: native repair, native repair + MPEG-PLGA, and native repair + MPEG-PLGA + MFF. MFF were labeled with PKH26-fluorescence dye. After 8 weeks labeled cells were identified in tissue samples and histopathological and immunohistochemical analyses of connective tissue organization and desmin reactivity of muscle cells were performed. Fresh tissue samples were subjected to uniaxial biomechanical testing. Statistical analyses were performed using one-way analysis of variance (ANOVA).

resultsMPEG-PLGA was fully degraded after 8 weeks. Desmin-immunopositive (6/6) and PKH26-positive cells (6/6) were found only after native repair + MPEG-PLGA + MFF, indicating survival, proliferation, and integration of cells originating from the MFF. This group also showed significantly increased stiffness in the high stiffness zone compared with native repair + MPEG-PLGA (p = 0.032) and borderline significantly higher stiffness compared to native repair (p = 0.054).

conclusionsIn this pilot study, MPEG-PLGA scaffolds seeded with autologous MFF affected some histological and biomechanical properties of native tissue repair in an abdominal wall defect model in rats. The method thus appears to be a simple tissue engineering concept with potential relevance for native tissue repair of POP.
