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

purposeThe purpose of this study was to perform a systematic review of randomized controlled trials comparing the results of matrix-induced chondrogenesis with other therapies for local chondral lesions of the knee.

methodsA systematic search for randomized controlled trials (RCT) about matrix-induced chondrogenesis for focal chondral lesions in the knee was performed according to the PRISMA guidelines. Data source was PubMed central, EMBASE and Google scholar.

resultsFive articles could be included, whereas two originated from the same study group. Three studies compared matrix-induced chondrogenesis to microfracture (MFx) only. One trial compared AMIC

conclusionResults of RCTs comparing matrix-induced chondrogenesis with other treatment options showed that matrix-induced chondrogenesis is a valid and safe cartilage repair option for small- to medium-sized cartilage defects of the knee. This one-stage surgical technique presents a good alternative for patients. LEVEL OF EVIDENCE: I.
