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

SAD-1 is a serine/threonine kinase which plays an important role in the regulation of both neuronal polarity and synapse formation in Caenorhabditis elegans. The kinase domain of SAD-1 from C. elegans was overexpressed in Escherichia coli BL21 (DE3) cells and purified to homogeneity using nickel-nitrilotriacetic acid metal-affinity, ion-exchange and gel-filtration chromatography. Diffraction-quality crystals were grown using the sitting-drop vapour-diffusion technique from a condition consisting of 1 M CAPSO pH 9.6, 10%(w/v) polyethylene glycol 3350. The crystals belonged to the monoclinic space group C2, with unit-cell parameters a = 205.4, b = 57.1, c = 71.7 Å, β = 106.1°. X-ray diffraction data were recorded to 3.0 Å resolution from a single crystal using synchrotron radiation.
