Satisfactory clinical and radiographic outcomes following revision total hip arthroplasty by direct anterior approach using primary femoral stems at 2-8 years of 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
introductionTo report clinical and radiographic outcomes of revision total hip arthroplasty (THA) through the direct anterior approach (DAA) using primary stems. MATERIALS AND
methodsThe authors assessed a consecutive series of revision THAs operated by DAA using primary (cemented and uncemented) stems between 1/1/2010 and 30/06/2017. The initial cohort comprised 47 patients (50 hips), aged 65 ± 10 years with BMI of 25 ± 4 kg/m
resultsOf the 50 hips (47 patients) in the initial cohort, intraoperative complications that did not require re-revision occurred in 5 hips. At a follow-up of > 2 years: 5 hips (10%) were lost to follow-up and 3 hips (6%) required stem re-revision, leaving a final cohort of 42 hips (40 patients). Postoperative complications that did not require re-revision occurred in 4 hips (8%). At 4.3 ± 1.6 years, post-revision mHHS was 89 ± 14 (range 47-100) and 38 patients were satisfied or very satisfied with revision surgery. Bone remodelling was observed in 8 hips (16%), cortical hypertrophy in 6 hips (12%), grade I heterotopic ossification in 7 hips (14%), and grade II in 1 hip (2%). There were no cases of radiolucent lines, pedestal formation, or osteolysis. Regression analyses revealed that post-revision mHHS was not associated with any variable.
conclusionsRevision THA performed through the DAA using primary stems grants satisfactory clinical and radiographic outcomes at a minimum follow-up of two years.
