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

Background: Most of the literature about soft-tissue coverage of open fractures is focused on Gustilo-Anderson IIIB/IIIC. A significant proportion of the flaps performed for coverage after open fractures is however performed for Gustilo-Anderson types I to IIIA which develop soft-tissue damage over days after injury. This study aims at analyzing this specific subset of open fractures regarding characteristics, management and outcomes. Methods: A retrospective study was conducted on patients who benefited from a pedicled or free flap coverage for open fractures of the lower extremity. Bone union and rate of deep infection were compared between patients presenting open fractures type I to IIIA (Lower Entity Gustilo-LEG) with secondary soft-tissue damage and patients who presented open fractures type IIIB and IIIC (Higher Entity Gustilo) with immediate soft-tissue damage. Results: Eighteen patients were included, seven of which were in the first group (LEG) and 11 in the second group (HEG). Time from injury to coverage was significantly longer for the LEG group (23.6 Conclusion: Open fractures of the lower extremities type Gustilo-Anderson I to IIIA (LEG) which develop soft-tissue damage after injury eventually requiring flap coverage seem to have a lower risk of deep infection and delayed union despite longer delay between trauma and coverage as well as between definitive fixation and coverage.
