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

Unstable pelvic ring injuries usually present with pubic symphysis and/or pubic rami disruption, in association with fractures or fracture-dislocations affecting the posterior iliac, sacroiliac joint, and/or the sacrum. Involvement of the strong posterior osteoligamentous complex with an intact anterior pelvic ring is extremely rare, with only a limited number of cases previously documented. We report the case of a 15-year-old male who sustained high-energy trauma after being struck in the back by a heavy metal structure. He presented with a unilateral posterior sacroiliac dislocation and an intact anterior pelvic ring, which is believed to represent a previously unreported injury. The patient underwent closed reduction with percutaneous fixation using a 7.0 mm partially threaded cannulated iliosacral screw. This case highlights an unusual pelvic injury pattern not fully addressed by current classification systems and emphasizes the importance of carefully assessing anterior ring integrity in high-energy posterior pelvic trauma.
