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

backgroundEarly postoperative complications after microvascular mandibular reconstruction impact outcomes in patients with advanced oral cancer. This study evaluates three reconstruction techniques: vascularized bone graft (VBG), mandibular reconstruction plate (MRP) with a non-osseous flap, and soft tissue flap (STF), using the Comprehensive Complication Index (CCI).

methodsIn this retrospective study of 101 patients, early postoperative complications (≤ 30 days) were assessed using the CCI, calculated from Clavien-Dindo classification grades. Differences among the three techniques were analyzed using multivariable linear regression.

resultsVBG was performed in younger, healthier patients. No significant differences in CCI were found among the three techniques. Multivariable analysis confirmed that non-surgical factors, such as diabetes, had greater influence on complication risks.

conclusionsAppropriate patient selection minimizes early complication risks. VBG in younger patients and technical refinements in MRP may yield complication burdens comparable to STF.

trial registrationThis study was registered in the UMIN Clinical Trials Registry as UMIN000056584 (http://www.umin.ac.jp/ctr).
