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

introductionSubchondral cysts are deeply related to the pathogenesis of osteoarthritis (OA), but the factors contributing to cyst formation are not well known. A three-dimensional analysis of subchondral cysts at the micro-structural level was conducted using a high-resolution peripheral quantitative CT (HR-pQCT), and their relationships with cartilage attrition and subchondral bone microstructure were investigated.

methodsFemoral heads extracted from ten female patients with hip OA were scanned using an HR-pQCT at a voxel size of 41μm. The volume fractions, numbers, and sizes of the cysts were measured in the subchondral bone region under the area of cartilage loss. Furthermore, the areas of cartilage loss, as well as the microstructure of the subchondral bones, were also measured, and their correlations with the cysts were analyzed.

resultsThe volume fractions of cysts within subchondral bone regions varied from 2% to 33%, the numbers of cysts varied from 6 to 87, and the sizes varied from 1mm(3) to 657mm(3). There was a positive correlation between the number of cysts and bone volume (r>0.8, p<0.01).

conclusionThe degree of cyst formation showed a wide distribution in number and volume, and there was a close relationship between multiple cyst formation and bone sclerosis, which might be caused by reactive bone formation that occurred around each cyst.
