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

introductionWe aimed to compare periprosthetic femoral bone remodeling after cementless total hip arthroplasty (THA) using a short-tapered wedge stem and a fully hydroxyapatite (HA)-coated stem. MATERIALS AND

methodsIn this retrospective study, 24 primary cementless THA procedures with short-tapered wedge stem and 24 using a fully HA-coated stem were performed. The follow-up duration was 2 years for both groups. Clinical evaluation was performed using the Merle d'Aubigné and Postel scoring systems. Standardized anteroposterior radiographs of the pelvis and femur were obtained. Dual-energy X-ray absorptiometry was performed, and the bone mineral density (BMD) around the stem was assessed in each Gruen zone at the first postoperative week as a baseline value and at 6 weeks, 3 and 6 months, and 1 and 2 years postoperatively.

resultsThe mean Merle d'Aubigné and Postel scores improved significantly postoperatively in both groups. None of the hips showed loosening in either group. Spot welds occurred in zones 1, 2, 6, and 7 in the short-tapered wedge group, and in all zones in the fully HA-coated group. Significant BMD loss occurred only in zone 4 in the short-tapered wedge group, and no significant bone loss occurred in any zone in the fully HA-coated stem group; a significant difference between the two groups was observed only in zone 4 at 2 years after THA.

conclusionsClinical and radiographical outcomes in both groups were good, and both stems suppressed postoperative BMD loss at 2 years.
