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

Background: The direct anterior approach (DAA) has become the most frequently utilized surgical approach for total hip arthroplasty (THA) in the United States. There is a growing need to clarify the differential risk of complications associated with the DAA compared to other surgical approaches. Heterotopic ossification (HO) is a well-recognized complication following THA that may result in pain and stiffness. Despite its clinical relevance, the risk of HO in DAA patients remains poorly described. In this review, we provide a comprehensive overview of HO following THA, with a particular focus on the DAA. Methods: A comprehensive literature search of the PubMed/Medline database was performed using search terms "total hip arthroplasty," "heterotopic ossification," and "approach." Article titles and abstracts were reviewed to determine relevance. Randomized controlled trials, systematic reviews, meta-analyses, comparative studies, and case series were included. Articles not published in the English language were excluded. Results: HO results from trauma-induced differentiation of osteoprogenitor cells in soft tissue surrounding the hip joint. Surgical approach is a determinant of HO risk after THA, with the DAA producing the lowest incidence of HO. Other risk factors for the development of HO have been identified, including male gender and advanced age. Prophylaxis against HO includes perioperative nonsteroidal anti-inflammatory drugs, tranexamic acid, and local radiation therapy, while management involves surgical resection of ectopic bone in symptomatic patients. Conclusions: This review synthesizes data from recent systematic reviews and case series to provide arthroplasty surgeons with an understanding of postoperative HO risk, stratified by surgical approach.
