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

objectiveMicrovascular coupler devices have been proven an effective alternative to standard hand-sutured anastomoses in reconstructive surgery. Until now, the influence of the coupler size on the revision rate after free flap tissue transfer in head and neck surgery has not been investigated. Neither has its influence on the timing of venous revisions. MATERIALS AND

methodsA retrospective mono-center cohort study was performed in order to analyze the influence of coupler size on timing and revision rate of microvascular procedures.

results437 patients who had undergone surgery between 2009 and 2015 were included. The statistical analysis of coupler size and revision rate due to venous complications showed a significant reduction of more than 40% in the revision rate for each additional mm in the coupler size. We observed revisions due to venous congestion until the fourth day postoperatively within our cohort. However, when the coupler size used was ≥ 3 mm, no venous congestion occurred later than 12 h after surgery.

conclusionThe quantitative effects of coupler size on the revision rate in head and neck reconstruction were demonstrated for the first time. We recommend spending extra time and effort on dissecting the largest possible vein in order to be able to choose the largest possible coupler size for the venous anastomosis. As a consequence of our findings, we limit our postoperative monitoring for patients with a coupler ≥ 3 mm to 24 h, as later venous congestions are very unlikely.
