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

Caged morpholino oligonucleotides (cMOs) are useful research tools in developmental biology because they allow spatiotemporal control of gene expression in whole organisms. While cMOs are usually triggered by light of a single wavelength, the introduction of spectrally distinct chromophores can enable combinatorial regulation of multiple genes. This chapter describes the general principles and methods of wavelength-selective cMO design and synthesis from commercially available reagents. Synthetic protocols for the linkers and the two-step cMO assembly are described in detail, as well as the microinjection and photoactivation techniques. Following these protocols, spectrally separated cyclic cMOs for multiple genes of interest can be prepared, enabling their inhibition in zebrafish embryos and other animal models.
