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

objectiveTo compare the long-term efficacy of screw fixation and hemiarthroplasty in elderly patients with undisplaced femoral neck fractures.

methodsWe searched Cochrane Library, EMBASE, and MEDLINE from inception to 10 June 2020 to identify studies about undisplaced femoral neck fracture in elderly patients over 65 years of age. The included studies were assessed by two researchers according to the Cochrane risk-of-bias criteria and Newcastle-Ottawa Scale. Meta-analysis was performed with Revman 5.3 software. The odds ratios (OR) and mean differences (MD) were used to compare dichotomous and continuous variables.

resultsA total of 750 patients were included in this meta-analysis. In elderly patients, undisplaced femoral neck fracture treated with hemiarthroplasty had a lower implant-related complication rate (OR, 4.05 [95% CI, 2.38 to 6.89]; P < 0.00001; I

conclusionIn elderly patients with undisplaced femoral neck fractures, hemiarthroplasty provided a lower implant-related complication rate, lower reoperation rate, superior hip function without increased long-term mortality. Hemiarthroplasty should be recommended as a better alternative in such patients compared with multiple cannulated screws.
