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

objectiveIn patients with varus deformity of the knee, the redistribution of the subchondral bone mineral density (BMD) of the tibia leads to sclerotic zones that may cause osteoarthritis. Drilling the sclerotic area of the tibia prior to cementing during total knee arthroplasty is advisable practice. However, the extent of the sclerotic area and the effect of drilling on the tibial component are not well defined. We aimed to quantify the BMD and sclerotic bone distribution of the knee to clarify the effect of drilling on the stability of the prosthesis.

methodsOur retrospective cohort study enrolled a total of 97 patients from December 2018 to December 2019, categorized into drilled and nondrilled groups, with their computed tomography (CT) knee joint images documented. The proximal tibia image was divided into nine regions, the BMD of each region calculated, and CT values compared between the affected and normal sides. We established finite element models to analyze the drilling and stress distribution. The differences in CT values were assessed using the paired t test and Wilcoxon signed-rank test.

resultsThe mean thickness of sclerotic bone was 7.7 ± 1.4 mm, and the surface area was 441.9 ± 89.4 mm

conclusionAbnormal stress in the proximal tibia alters the distribution pattern of BMD, and drilling in the sclerotic area is associated with improved prosthesis stability.
