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

purposeSimultaneous ipsilateral sacroiliac joint (SIJ) injury and acetabular fracture are relatively common. Inadequate SIJ reduction may compromise the anatomical alignment of associated acetabular fractures. However, the optimal surgical approach for managing both injuries remains uncertain. In this study, we aimed to compare the efficacy of pelvic ring injury reduction using either the lateral window or the pararectus approach and to analyze associated radiological outcomes in patients with concurrent SIJ injury and acetabular fracture.

methodsThis retrospective study included 44 patients who underwent open reduction and internal fixation (ORIF) for SIJ injury. Patients were divided into two groups based on the surgical approach: L group (lateral window of the ilioinguinal approach) and P group (pararectus approach). A subgroup of patients with simultaneous ipsilateral SIJ injury and acetabular fracture was selected for comparative analysis using postoperative computed tomography (CT) to assess SIJ reduction and acetabular fracture alignment.

resultsImprovements in SIJ distance on axial and coronal CT planes were observed in both groups, with greater reductions observed in the P group. Among patients with combined injuries, the P group demonstrated significantly improved SIJ reduction in the coronal plane (P = 0.008), which was associated with smaller residual fracture gaps and articular step-offs in the axial, coronal, and sagittal planes.

conclusionWhen ORIF is indicated for SIJ injury, the pararectus approach may offer enhanced SIJ reduction in the coronal plane. This technique is also associated with improved acetabular fracture alignment in patients with simultaneous ipsilateral injuries.
