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

Ectoine is widely produced by various bacteria as a natural cell protectant against environment stress, e.g., osmotic and temperature stress. Its protective properties therefore exhibit high commercial value, especially in agriculture, medicine, cosmetics, and biotechnology. Here, we successfully constructed an engineered Escherichia coli for the heterologous production of ectoine. Firstly, the ectABC genes from Halomonas elongata were introduced into E. coli MG1655 to produce ectoine without high osmolarity. Subsequently, lysA gene was deleted to weaken the competitive L-lysine biosynthesis pathway and ectoine bioconversion was further optimized, leading to an increase of ectoine titer by 16.85-fold. Finally, at the low cell density of 5 OD
