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

Periprosthetic femoral fracture (PFF) and stem subsidence are major early complications following cementless total hip arthroplasty (THA). However, few studies have compared these complications between different femoral stem designs after adjusting for patient characteristics. This study compared the incidence of PFF and stem subsidence between fit-and-fill and tapered-wedge stems in primary cementless THA. A total of 753 THAs using a fit-and-fill stem and 526 using a tapered-wedge stem performed between January 2013 and June 2020 were retrospectively reviewed. Patient demographics, radiographic findings, and perioperative complications were analyzed using univariate, multivariate, and propensity score-matched analyses. Propensity score matching was performed for age, sex, body mass index, and femoral morphology (Dorr type), resulting in 478 matched THAs in each group. After matching, the rates of perioperative PFF were 2.3% in the fit-and-fill group and 0.6% in the tapered-wedge group (P = 0.026; 95% confidence interval [CI]: 1.0-13.5, odds ratio [OR]: 3.7). The rates of ≥ 2-mm stem subsidence were 7.2% and 1.5%, respectively (P = < 0.001; 95% CI: 2.2-11.7, OR: 5.2). These findings suggest that tapered-wedge stems are associated with lower rates of early femoral complications such as PFF and stem subsidence than fit-and-fill stems in cementless THA.
