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

backgroundMaxillofacial reconstruction with vascularized bone restores facial contour and provides structural support and a foundation for dental rehabilitation. Routine implant placement in such cases, however, remains uncommon. This study aims to determine dental implant survival in patients undergoing vascularized maxillary or mandibular reconstruction through a systematic review of the literature.

methodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the literature was queried for implant placement in reconstructed jaws using Medical Subject Headings terms on PubMed, Embase, and Cochrane platforms. Weighted implant survivals were calculated for the entire cohort and subcohorts stratified by radiotherapy. Meta-analyses were performed to estimate effect of radiation on implant osseointegration.

resultsOf 3965 publications identified, 42 were reviewed, including 1084 patients with 3636 dental implants. Weighted implant survival was 92.2 percent at a median follow-up of 36 months. Survival was 97.0 percent in 269 implants placed immediately in 60 patients versus 89.9 percent in 1897 delayed implants placed in 597 patients, with follow-up of 14 and 40 months, respectively. Dental implants without radiotherapy exposure had better survival than those exposed to radiation (95.3 versus 84.6 percent; p < 0.01) at a median follow-up of 36 months. Meta-analyses showed that radiation significantly increased the risk of implant failure (risk ratio, 4.74; p < 0.01) and suggested that implants placed before radiotherapy trended toward better survival (88.9 percent versus 83.4 percent, p = 0.07; risk ratio, 0.52; p = 0.14).

conclusionsOverall implant survival was 92.2 percent; however, radiotherapy adversely impacted outcomes. Implants placed before radiotherapy may demonstrate superior survival than implants placed after.
