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

The effect of the friction coefficient between bone cement and polished stems on stem subsidence was investigated in total hip arthroplasty (THA) using nonlinear finite element analysis. Stem subsidence results from both stem slip and shear deformation of the cement. On the lateral side, subsidence is mainly caused by stem slip, while on the medial side, cement deformation is involved. With low friction coefficients, "Reverse subsidence" occurs after load release, where the stem moves upward, and compressive stress is transmitted to the cement. On the other hand, with high friction coefficients, more significant shear deformation of the cement mantle occurs, and residual strain accumulates in the proximal region. The present study implies a trade-off relationship: high friction increases the risk of periprosthetic fractures (PPFs) in the proximal region, while low friction increases the risk in the distal region.
