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

22-Hydroxy-23,24-bisnorchol-4-ene-3-one (4-HBC) and 3-oxo-4,17-pregnadiene-20-carboxylic acid methyl ester (PDCE) are useful precursors for the synthesis of steroidal active pharmaceutical ingredients. In this study, we identify the sterol metabolism-related genes, which encode the aldolases (Ltp2 and Thl) and carboxylic acid reductases (CAR) in Mycolicibacterium neoaurum NRRL B-3805 (B3805), by analysis of the metabolites from phytosterols biotransformation. Based on these results, a genetically modified strain is constructed by disrupting the kstD, ltp2, and hsd4A genes and overexpressing the aldolase gene (thl) in the strain B3805. This recombinant strain (B3805V) is able to transform 5 g L
