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

backgroundThe quality of reduction is an important factor affecting clinical outcomes for displaced femoral neck fractures (FNFs). However, concerns remain about the invasiveness of open reduction and internal fixation (ORIF) as compared to that of closed reduction and internal fixation (CRIF), and the choice between ORIF and CRIF as an optimal treatment strategy for displaced pediatric FNF remains controversial. MATERIALS AND

methodsMEDLINE, Embase, and the Cochrane Library were systematically searched for studies published up to December 22, 2022, that compared ORIF and CRIF techniques for treating FNF in children. Pooled analysis identified differences in surgical outcomes between ORIF and CRIF, especially regarding postoperative complications, such as osteonecrosis of the femoral head (ONFH), nonunion, coxa vara deformity, leg-length discrepancy LLD, and premature physeal closure (PPC).

resultsWe included 15 studies with 635 pediatric FNF cases in our review. Of these, 324 and 311 were treated with ORIF and CRIF, respectively. The pooled analysis revealed that no significant differences existed between each reduction technique for ONFH (odds ratio [OR] = 0.89; 95% confidence interval [CI] 0.51-1.56; P = 0.69), nonunion (OR = 0.51; 95% CI 0.18-1.47; P = 0.21), coxa vara deformity (OR = 0.58; 95% CI 0.20-1.72; P = 0.33), LLD (OR = 0.57; 95% CI 0.18-1.82; P = 0.35), and PPC (OR = 0.72; 95% CI 0.11-4.92; P = 0.74).

conclusionsDespite concerns about the invasiveness of ORIF, no differences in complications exist between ORIF and CRIF after FNF in children. Therefore, we believe that ORIF should be performed in FNF when the fracture is irreducible by closed manner.
