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

The cobweb spider Parasteatoda tepidariorum (C. L. Koch, 1841; syn.: Achaearanea tepidariorum) has become an important study organism in developmental biology and evolution as well as in genetics. Besides Cupiennius salei, it has become a chelicerate model organism for evo-devo studies in recent years. However, a staging system taking into account the entire development, and detailed enough to apply to modern studies, is still required. Here we describe the embryonic development of P. tepidariorum and provide a staging system which allows easy recognition of the distinct stages using simple laboratory tools. Differences between P. tepidariorum and other chelicerates, primarily C. salei, are discussed. Furthermore, cocoon production and the first postembryonic moulting procedure are described. Schematic drawings of all stages are provided to ease stage recognition.
