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

Management of periacetabular osteolysis is a challenging dilemma in revision total hip arthroplasty. When the acetabular shell is well-fixed, the surgeon may prefer to retain the cup to minimize further bone loss. However, filling the surrounding defect can be difficult if the area of involvement is massive. In this case, holes were created in the existing acetabular cup for supplemental pelvic screws, which were placed using computed tomography navigation, and then the areas of osteolysis were filled with cement. The patient recovered uneventfully, and he was satisfied with the outcome at 4 years postoperatively. Thus, pelvic screw placement with cement augmentation could be a viable option for a stable cup with surrounding osteolysis. Patient selection should be considered carefully as the long-term outcomes of this procedure are unknown.
