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

backgroundThis meta-analysis compared clinical outcomes of arthroplasty vs. osteosynthesis for displaced femoral neck fractures.

methodsMeta-analysis was performed on the difference in revision rate and overall mortality between participants undergoing osteosynthesis vs. total hip arthroplasty (THA), osteosynthesis vs. hemiarthroplasty (HA), or THA vs. HA.

resultsPooled direct and indirect results indicated no significant difference in mortality between THA and HA (pooled OR = 0.87, 95% CI 0.55 to 1.38; P = 0.556), between THA and osteosynthesis (pooled OR = 1.17, 95% CI 0.69 to 1.99; P = 0.553), and between HA and osteosynthesis (pooled OR = 1.21, 95% CI 0.84 to 1.74; P = 0.304). Pooled direct and indirect results indicated no significant difference in revision rates between THA and HA (pooled OR = 0.90, 95% CI 0.26 to 3.19; P = 0.874). But, fewer revisions (OR = 0.19, 95% CI 0.10 to 0.34; P = 0.000) were seen in patients treated with THA than osteosynthesis and also in those treated with HA than osteosynthesis (OR = 0.12, 95% CI 0.07 to 0.20; P = 0.000). After excluding studies without showing normal cognition in inclusion criteria, pooled direct and indirect results also indicated no significant difference in mortality between THA, HA, and osteosynthesis. Similarly, there was no significant difference in revision rates between THA and HA, but HA and THA had significantly lower revision rates compared with osteosynthesis.

conclusionsThere was no significant difference in overall mortality among osteosynthesis, HA, and THA. However, HA and THA had significantly lower revision rates compared with osteosynthesis. Results of the present study provide support for the use of hip arthroplasty to treat displaced fractures of the femoral neck.
