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

Segmental flow in the human trabecular meshwork is a well-documented phenomenon but in depth mechanistic investigations of high flow (HF) and low flow (LF) regions are restricted due to the small amount of tissue available from a single donor. To address this issue we have generated and characterized multiple paired HF and LF cell strains. Here paired HF and LF cell strains were generated from single donors. Cells were characterized for growth and proliferation, as well as gene and protein expression of potential segmental region markers. Cells isolated from HF and LF regions have similar growth and proliferation rates. Gene expression data reveals vascular cell adhesion protein 1 (VCAM1), thrombospondin 2 (THBS2), and tissue inhibitor of metalloproteinase 1 (TIMP1) are potential markers of LF cells in vitro. Protein expression of VCAM1, THBS2 and TIMP1 are complex and may reflect the dynamic nature of the TM. Initial protein expression levels of these genes is either similar between HF and LF cells (VCAM1, THBS2), or higher in HF compared to LF in some strains (TIMP1). However, after long term culture LF cells express higher levels of VCAM1, TIMP1 and THBS2 protein compared to HF cells. HF and LF cell strains are a powerful new tool that enable understanding segmental flow allowing for multiple experiments on the same genetic background.
