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

Accumulating evidence suggests that oxidative stress plays an important role in the progression of osteoarthritis (OA), and pyrroloquinoline quinone (PQQ) is considered a strong antioxidant. However, it is unclear whether PQQ can prevent the progression of OA by inhibiting oxidative stress. In this study, anterior cruciate ligament transection (ACLT)-induced OA mice received a diet supplemented with/without PQQ, and were compared with each other and with sham-operated mice. Our results showed that in PQQ-untreated OA mice, articular surfaces collapsed, while the thickness of articular cartilage and the abundance of cartilage matrix protein decreased significantly, whereas PQQ supplementation largely prevented these alterations. We also found that oxidative stress, DNA damage, cellular senescence and the secretion of senescence-associated inflammatory cytokines were increased in PQQ-untreated OA mice compared with sham-operated mice. However, these parameters were obviously rescued in PQQ-treated OA mice. This study demonstrated that PQQ supplementation can prevent ACLT-induced OA by inhibiting oxidative stress, DNA damage, cell senescence and the development of the senescence-associated secretory phenotype.
