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

purposeTotal hip arthroplasty with a dual mobility cup (DMC) is a proposed alternative to the widely performed bipolar hemiarthroplasty (BHA) for treating displaced intracapsular femoral neck fractures (DFNF) in the elderly. However, the comparison between the two modalities has not been extensively conducted thus far.

methodsA retrospective cohort study was conducted with DFNF patients aged over 65 years who were treated either by BHA or DMC. After propensity matching each group comprised 84 patients (168 patients in total) and was analyzed using peri-operative and post-operative parameters.

resultsMean follow-up durations were 22.1 and 21.7 months in the BHA and DMC groups, respectively. The BHA group demonstrated significantly less intra-operative blood loss (p = 0.001) and a shorter length of operation (p < 0.001). However, there was no difference in one-year mortality (p = 0.773). The Harris hip score (HHS) was significantly higher (p = 0.018) in the DMC group. The dislocation rate was not different between the two groups (p = 1.000).

conclusionIn DFNF patients aged over 65 years, short-term observation showed DMC to be the preferred treatment over BHA with better clinical outcome, without disadvantages in mortality or dislocation rate. Further long-term investigations are recommended to strengthen these results.
