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

introductionRecently, bone-active factors such as parathyroid hormone and lactoferrin, have been used in pre-clinical models to promote tendon healing. How-ever, there is limited understanding of how these boneactive factors may affect the cells of the ten-don themselves. Here, we present an in vitro study assessing the effects of parathyroid hor-mone and lactoferrin on primary tendon cells (tenocytes), and compare their responses to the tenogenic factors, PDGF, IGF-1 and TGF-β. MATERIALS AND

methodsTenocyte proliferation and collagen production were assessed by alamarBlue® and Sirius red as-says, respectively. To assess tenocyte trans-differentiation, changes in the expression of genes important in tenocyte, chondrocyte and osteoblast biology were determined using real-time PCR.

resultsParathyroid hormone and lactoferrin had no effect on tenocyte growth or collagen production, with minimal changes in gene expression and no detrimental effects observed to suggest trans-differentiation away from tendon cell behaviour. Tenogenic factors PDGF, IGF-1 and TGF all increasetenocyte collagen production, however, the gene expression data suggests that PDGF promotes severe de-differentiation of the tenocytes. DISCUSSION: Our findings suggest that using parathyroid hormone or lactoferrin as a singular factor to promote tendon healing may not be of benefit, but for use in tendon-bone healing there would be no detrimental effect on the tendon itself.
