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

A novel three-step synthetic approach for modification of betulin at position C-30 was developed starting from commercially available betulin diacetate. The scope of this procedure exceeds significantly the previously used methods while providing higher yields. The final Mitsunobu reaction was the pivotal step of the synthesis, and after optimization, 39 new derivativesethers, esters, and amineswere synthesized in good to high yields. All the novel compounds were tested for
