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

Synthetic endoperoxide antimalarials, such as 1,2,4-trioxolanes and 1,2,4,5-tetraoxanes, are promising successors for current front-line antimalarials, semisynthetic artemisinin derivatives. However, limited solubility of second-generation analogues in biological-relevant media represents a barrier in clinical development. We present methodology for the synthesis of nonlinear analogues of second-generation tetraoxane antimalarials E209 and N205 to investigate reduced molecular symmetry on in vitro antimalarial activity and physicochemical properties. While maintaining good antimalarial activity and metabolic stability, head-to-head comparison of linear and nonlinear counterparts showed up to 10-fold improvement in FaSSIF solubility for three of the four analogues studied.
