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

objectiveTo evaluate the long-term results of the use of nerve growth factor (NGF)-loaded poly-D, L-lactide-co-glycolide (PLGA) microspheres for improve nerve regeneration with small gap tubulization.

methodsNGF microspheres were prepared by a modified W/O/W emulsion solvent evaporation method. Forty-eight male SD rats were separated into 4 groups and received a chitin conduit to bridge a sciatic nerve injury left a 2 mm gap. Saline (Group A), 20 ng/ml NGF solution (Group B), blank PLGA microspheres (Group C), or 40 ng/ml NGF-loaded microspheres (Group D) was injected in the gap. Each group had two study endpoints, 3 months subgroup and 1 year subgroup.

resultsThe myelinated fiber count at 2 mm distal to the conduit at 1 year was slightly less than at 3 months in all groups (P>0.05). However, the maturity of the myelinated nerves at 1 year was obviously improved. The fiber count, myelin sheath thickness, axon area of NGF microsphere group were significantly higher than the saline groups at 3 months (P=0.05, P<0.05, and P<0.05, respectively). The SFI was significantly improved in NGF microspheres group compared to the saline group and NGF solution group at 1 year (P<0.05, and P<0.05, respectively).

conclusionsThe results demonstrated that the release of NGF microspheres in small gap tubulization benefit on peripheral nerve injury facilitated nerve regeneration histologically, especially for the maturity of early regenerative nerve fibers and also had an effect on functional recovery in the long term.
