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

Intramolecular Diels-Alder reactions have been extensively used for the syntheses of biologically active compounds including natural products. We have identified Co(I) complexes and optimal reaction conditions to accomplish highly diastereo- and enantioselective intramolecular [4+2]-cycloaddition reactions of 1,3-diene-ynes and 1,3-diene-enes. These catalysts, readily prepared from an earth-abundant metal and tunable ligands, serve as practical replacements for the prohibitively expensive Rh-complexes previously used for similar reactions. The cationic complexes are readily prepared by the reaction of LCoX
