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

In vivo, keratocytes are surrounded by aligned type I collagen fibrils that are organized into lamellae. A growing body of literature suggests that the unique topography of the corneal stroma is an important regulator of keratocyte behavior. In this study we describe a microfluidic method to deposit aligned fibrils of type I collagen onto glass coverslips. This high-throughput method allowed for the simultaneous coating of up to eight substrates with aligned collagen fibrils. When these substrates were integrated into a PDMS microwell culture system they provided a platform for high-resolution imaging of keratocyte behavior. Through the use of wide-field fluorescence and differential interference contrast microscopy, we observed that the density of collagen fibrils deposited was dependent upon both the perfusion shear rate of collagen and the time of perfusion. In contrast, a similar degree of fibril alignment was observed over a range of shear rates. When primary normal rabbit keratocytes (NRK) were seeded on substrates with a high density of aligned collagen fibrils and cultured in the presence of platelet derived growth factor (PDGF) the keratocytes displayed an elongated cell body that was co-aligned with the underlying collagen fibrils. In contrast, when NRK were cultured on substrates with a low density of aligned collagen fibrils, the cells showed no preferential orientation. These results suggest that this simple and inexpensive method can provide a general platform to study how simultaneous exposure to topographical and soluble cues influence cell behavior.
