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

purposeThe aim of surgical treatment for lateral compression type 2 (LC-2) pelvic fractures is to enable early mobilization and provide pain relief. Anterior and posterior ring fixation is usually performed simultaneously, with the goal of providing good biomechanical stability. However, it is unclear whether anterior ring fixation is necessary. This study therefore aimed to determine the feasibility of isolated posterior ring fixation for LC-2 pelvic fractures.

methodsRecords of patients with LC-2 pelvic fractures were extracted from a medical database. Patients who underwent posterior pelvic ring fixation alone (PR fixation group) or anterior and posterior ring fixation (APR fixation group) were included. Patients' operative characteristics, time to clinical healing, length of hospital stay, time to weight bearing, and complications were recorded at follow-up. Radiography was used to assess healing and fracture displacement. Functional outcomes were evaluated using the Majeed grading system.

resultsThe PR fixation group included 44 patients, and the APR fixation group included 49 patients. Operative time, intra-operative blood loss, units of blood transfused, intra-operative fluid administered, and post-operative drainage were lower in the PR fixation group than in the APR fixation group. Length of hospital stay was also shorter in the PR fixation group than in the APR fixation group. Although the frequency (8/44) of fracture displacement in the superior ramus prior to union was high in the PR fixation group, no significant differences in time to weight bearing, time to clinical healing, or Majeed scores were found between the groups at follow-up.

conclusionsIsolated posterior ring fixation for LC-2 pelvic fractures is feasible; patients who underwent treatment with this technique had functional outcomes similar to that of those who underwent anterior and posterior ring fixation.
