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

aimTo investigate whether early re-entry surgery following simultaneous guided bone regeneration (GBR) and implant placement has a negative impact on the outcome of bone regeneration and osseointegration. MATERIALS AND

methodsIn the edentulous mandible of six mongrel dogs, buccal peri-implant dehiscence defects were surgically created. Bone-level implants were placed with GBR, followed by submerged healing. Two experimental groups were randomly assigned according to the timing of re-entry and healing abutment connection at 2 months (early group) and 4 months (late group) following GBR. All animals were euthanised 5 months after GBR for histological analysis.

resultsOne implant in the late group failed as a result of fibrin incarceration. There was no statistically significant difference between the two groups regarding new bone area (1.98 mm

conclusionEarly second-stage surgery results in similar bone regeneration, osseointegration and mucosal dimensions as late abutment connection.
