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

Reactive oxygen species (ROS) and nitric oxide (NO) have been implicated in chondrocyte senescence and cartilage aging, pathogenesis of osteoarthritis (OA), and rheumatoid arthritis. Naturally occurring polyphenolic compounds (PPCs), such as curcumin (turmeric), resveratrol (grape), and epigallocatechin-3-gallate (EGCG) (green tea), have been known for their anti-inflammatory and chondroprotective effects. However, the potential protective effects of these PPCs against oxidative stress in chondrocytes are unclear. To investigate this, bovine articular chondrocytes and human osteoarthritic chondrocytes were pre-treated with PPCs at varying concentrations, and then exposed to hydrogen peroxide (H
