Conversion of failed proximal femoral nail antirotation to uncemented or cemented femoral component fixation: a multicentre retrospective study with a median 10-year follow-up.

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.
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
backgroundConversion of a failed proximal femoral nail antirotation (PFNA) to a total hip arthroplasty (THA) is becoming increasingly universal. However, consensus has not been reached regarding which device (uncemented or hybrid THA) to use. The aim of this retrospective study was to compare the clinical outcomes of the conversion of failed PFNAs to uncemented versus hybrid THAs in the elderly population.
methodsConsecutive elderly patients with prior failed PFNAs treated with uncemented or hybrid THA from January 2008 to December 2019 were retrospectively identified from two medical centres. The primary outcome was implant survival after THA revision; secondary outcomes were the functional outcomes assessed using the Harris Hip Score (HHS) and the incidence of key THA-related complications.
resultsA total of 236 patients (uncemented THA, n = 116; hybrid THA, n = 120) were eligible for this study. Kaplan-Meier survival curves demonstrated that the 10-year cumulative survival rates were 0.801 (95% confidence interval [CI], 0.783-0.852) in the uncemented THA group versus 0.925 (95% CI, 0.861-0.964) in the hybrid THA group (hazard ratio [HR] 0.36 [95% CI 0.24-0.56], p = 0.004). From the 72nd month after the revision to the last follow-up, functional outcomes differed considerably between cohorts (each p < 0.05), and the rate of key THA-related complications was comparable between cohorts (p = 0.004).
conclusionFor elderly patients with prior failed PFNAs who experienced uncemented or hybrid THA, hybrid THA revision may provide a clinically significant improvement over uncemented THA revision with regard to implant survival, functional outcomes, and THA-related complications compared to uncemented THA revision.
