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

objectivesThe aim of the present study was to assess the effect of dual growth factor release from collagen-based polyelectrolyte multilayer films (PEMs) on titanium implants on periimplant bone formation and angiogenetic activity in minipig mandibles. MATERIAL AND

methodsDisc shaped Ti implants (5 × 7 × 1 mm) were coated with polyelectrolyte multilayer films and loaded with rhBMP-2, rhVEGF165, and a combination of both. Uncoated and unloaded Ti implants served as controls. The implants were inserted press-fit into 5 mm trephine cavities in minipig mandibles and evaluated after 4 and 13 weeks for bone formation, bone implant contact, and periimplant expression of CD31.

resultsAfter 4 weeks, there was no significant difference in periimplant bone formation nor bone-implant contact between the different surface conditions. CD31 expression was significantly increased around PEM coated implants loaded with VEGF and BMP each. After 13 weeks, bone implant contact and bone formation were significantly increased only around PEM coated implants with simultaneous release of BMP-2 and VEGF165. Expression of CD31 was significantly enhanced around all PEM coated implants loaded with growth factors regardless of the type or combination.

conclusionIt is concluded that simultaneous release of rhBMP-2 and rhVEGF165 may be required to achieve significant improvement of periimplant bone formation and bone implant contact. Angiogenesis as reflected by CD31 expression is enhanced by both rhVEGF165 and rhBMP-2 to a similar extent without an additive effect of simultaneous release.
