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

Purpose: The laser-induced choroidal neovascularization (CNV) mouse model is the most frequently used animal model of CNV. To test new therapeutic agents that suppress CNV, CNV measurement in an accurate, precise, and efficient manner is important. We present the utility of Fiji-assisted automatic volumetric quantification of CNV in comparison with two-dimensional CNV analyses. Methods: Laser-induced CNV was induced in C57BL/6J mice according to the established protocol. After CNV induction, mice were treated with intravitreal injection of either phosphate-buffered saline solution (PBS) or Aflibercept, an anti- vascular endothelial growth factor agent. One week after intravitreal injection treatment, retina pigment epithelium/choroid flat mounts were stained with rhodamine-conjugated Griffonia simplicifolia lectin B4. Z-stacks of the entire CNV lesion obtained using laser confocal microscopy were converted to binary stacks using Fiji for volumetric analysis. Data from volumetric analysis and multiple area analyses from z-stack projection, the maximum, blindly selected, and mean area were compared using Fiji. Results: Fiji-assisted automatic quantitative volumetric analysis of CNV was useful in detecting experimental outliers in laser-induced CNV genesis and provided accurate and precise measurements of total areas of CNV with a lower coefficient of variance (63%) than in multiple area analyses, including the z-stack projection, maximum, blindly selected, and mean areas (67%, 67%, 76%, and 69%, respectively). A lower coefficient of variance in volumetric analysis than in multiple area analyses resulted in increased statistical significance when comparing CNV lesions in PBS, and Aflibercept-treated groups; P = 0.004 in volumetric analysis versus P value range between 0.03 and 0.05 in multiple area analyses. Conclusions: Fiji-assisted automatic quantitative volumetric analysis can be useful for accurate, precise, and efficient measurements of total areas of CNV. Translational Relevance: Volumetric measurement for CNV lesions can be advantageous in verifying the efficacy of therapeutic agents in the laser-induced CNV mouse model.
