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

objectiveThe aim of this study was to investigate whether collagenase clostridium histolyticum (CCH) reduces intra-articular fibrotic adhesion formation in a rat model of arthrofibrosis.

methodsA total of 24 male Wistar rats (7 months old, weighing 220 -275 g) were randomly and equally assigned to one of two groups: the collagenase group and the control group (n = 12 each). In each group, a partial capsulotomy, and synovectomy were performed in knee. After a partial capsulotomy and synovectomy were performed in each group, the collagenase group received intra-articular CCH of 0.008 mg in 0.1 mL saline solution while the control group received the equal volume of intra-articular saline solution alone. After 6 weeks of surgery, the rats were sacrificed by decapitation, and the following outcome measures were collected. Knee range of motion (ROM) was measured using with a goniometer under 20 g force. Adhesion formation was rated using the macroscopic visual scoring system after the knee joint was exposed through a lateral parapatellar approach. Histological evaluation was performed on samples including connective tissue and fibrotic adhesions, and fibroblast cell numbers were measured performed per square. Levels of interleukin 1 (IL-1) and fibroblast growth factor (FGF) were assayed by ELISA from the intra-articular fluid.

resultsThe macroscopic visual scoring system was significantly lower in the collagenasegroup (median = 1, range = 0-2) than in the control group (median = 2, range = 1-3)( < 0.001).ROMwas significantly higher in the collagenase group (102° ± 12.1°) than in the control group (77° ±8.94°) (P <0.001). The number of fibroblasts obtained from the scar tissue were considerably lower in the collagenase group (mean = 16.5 ± 2.74) compared tothe control group (mean = 30.1± 4.89) (P < 0.001). Levels of IL-1 andFGF were significantly lower in the collagenase group (mean = 18.6 ng/l ± 4.39,mean = 36.3 ng/l ± 2.03; respectively) compared to the control group (mean = 31.7ng/l ± 3.75, mean = 38.7 ng/l ± 2.19; respectively) (P < 0.001).

conclusionEvidence from this study has revealed that CCH injection can inhibit the development ofarthrofibrosis, decreasing the precursor inflammatory cytokines (IL-1 and FGF-1) and histologic fibrosis in a rat knee arthrofibrosis model. LEVEL OF EVIDENCE: Level IV, Therapeutic study.
