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

We determine the effect of interleukin (IL)-17 neutralizing antibody on new bone regeneration. Anti-IL-17 antibody promoted new bone regeneration in cortical bone defect model by augmenting FOXO1 and ATF4 activity thereby decreasing oxidative stress. Our study demonstrates the bone healing and regeneration potential of neutralizing IL-17antibody in osteoporotic fractures.

introductionThe immune system plays important role in the fracture healing process. However, fracture healing is prolonged in disorders associated with systemic inflammation. Fracture healing is decelerated in osteoporosis, condition linked with systemic inflammation. Bone regeneration therapies like recombinant human BMP2 are associated with serious side effects. Studies have been carried out where agents like denosumab and infliximab enhance bone regeneration in osteoporotic conditions. Our previous studies show the osteoprotective and immunoprotective effects of neutralizing IL-17 antibody. Here, we determine the effect of IL-17 neutralizing antibody on new bone regeneration and compare its efficacy with known osteoporotic therapies.

methodsFor the study, female BALB/c mice were ovariectomized or sham operated and left for a month followed by a 0.6-mm drill-hole injury in femur mid-diaphysis. The treatment was commenced next day onwards with anti-IL-17, anti-RANKL (Receptor activator of nuclear factor kappa-B ligand), parathyroid hormone (PTH), or alendronate for a period of 3, 10, or 21 days. Animals were then autopsied, and femur bones were dissected out for micro-CT scanning, confocal microscopy, and gene and protein expression studies.

resultsMicro-CT analysis showed that anti-IL-17 antibody promoted bone healing at days 10 and 21, and the healing effect observed was significantly better than Ovx, anti-RANKL antibody, and ALN, and equal to PTH. Anti-IL-17 also enhanced new bone regeneration as assessed by calcein-labeling studies. Additionally, anti-IL-17 therapy enhanced expression of osteogenic markers and decreased oxidative stress at the injury site.

conclusionOverall, our study demonstrates bone healing and regeneration potential of neutralizing IL-17 antibody in osteoporotic fractures.
