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

backgroundTantalum rods have been used in osteonecrosis of the femoral head (ONFH) for several years, while Zimmer trabecular metal implants have been proposed as the best choice. The aim of this study was to evaluate the effect of a new porous tantalum rod on the treatment of early ONFH.

methodsFrom July 2014 to December 2015, 19 patients (21 hips) were treated with Runze tantalum rod, and 20 patients (20 hips) received Zimmer tantalum prosthesis. All patients were followed up for at least 3 years.

resultsThere was no significant difference in demographic characteristics and the Harris Hip Score (HHS) improvement between the two groups. Kaplan-Meier analysis did not show any statistically significant difference in survival rates. One case in the Runze group had persistent pain and required conversion to total hip arthroplasty (THA) 8 months post-surgery. Histological evaluations revealed the presence of abundant new bone ingrowth into pores of the tantalum. The osteonecrosis observed in other patients was almost unchanged. At final follow-up, progressive collapse of the femoral head or the apparent joint space narrowing had not occurred.

conclusionsCompared with the traditional implants, implantation of the Chinese tantalum rod in the treatment of Association Research Circulation Osseous (ARCO) stages I, and II ONFH demonstrated highly encouraging clinical results.
