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

Osteochondral defects represent a significant clinical challenge due to the complex, graded architecture of the osteochondral unit and the limited regenerative capacity of articular cartilage. Gradient hydrogels have emerged as a promising class of biomimetic scaffolds that replicate the continuous transitions in structure, mechanics, composition, and biochemistry spanning from cartilage to subchondral bone. This review comprehensively examines recent advances in gradient hydrogel design for osteochondral regeneration. We discuss fundamental design principles encompassing structural porosity gradients, mechanical stiffness gradients (kPa-to-GPa transitions), compositional mineral gradients, and biochemical growth factor gradients, as well as their multi-dimensional integration. Fabrication strategies-including layer-by-layer assembly, 3D bioprinting, microfluidic generation, diffusion-based methods, and injectable
