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: We aim to report the consecutive patients diagnosed with osteonecrosis of femoral head (ONFH) following recovery from COVID-19 disease and elucidate the unique features of ONFH associated with COVID-19. Methods: Consecutive 22 patients (39 hips) recovered from COVID-19 and presented with ONFH from November 2020 to October 2021 were included. All the patients received corticosteroids as a supportive treatment during COVID-19. Patients were classified into two types based on the type of presentation, namely classic ONFH and rapidly destructive coxarthrosis (RDC) depending on radiographs, MRI, inflammatory markers and hip aspiration findings. Harris hip score was used to evaluate the functional outcome before and after treatment. Results: The mean time to diagnose of ONFH from the onset of hip symptoms was 39.3 days (range 10-90 days). The average duration of onset of hip symptoms after COVID 19 infection was 7.5 months (range 3 - 11 months). The average cumulative dose of methylprednisolone equivalent was 811 mg (range 200-2100 mg) and the average duration of steroid intake was 2.8 weeks. There was significant elevation in the inflammatory markers in RDC group compared to classic ONFH ( Conclusion: ONFH after COVID-19 can have a varied presentation. While the most common presentation is like classical ONFH, some patients can have an acute and aggressive presentation with rapid destruction. They have features like elevated serological markers and extensive periarticular bone and soft tissue edema. A low cumulative dose of steroids in our patients suggests that the COVID-19-associated vasculitis may play a role in the pathogenesis of ONFH.
