The mycobacterial desaturase DesA2 is associated with mycolic acid biosynthesis.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Mycolic acids are critical for the survival and virulence of Mycobacterium tuberculosis, the causative agent of tuberculosis. Double bond formation in the merochain of mycolic acids remains poorly understood, though we have previously shown desA1, encoding an aerobic desaturase, is involved in mycolic acid desaturation. Here we show that a second desaturase encoded by desA2 is also involved in mycolate biosynthesis. DesA2 is essential for growth of the fast-growing Mycobacterium smegmatis in laboratory media. Conditional depletion of DesA2 led to a decrease in mycolic acid biosynthesis and loss of mycobacterial viability. Additionally, DesA2-depleted cells also accumulated fatty acids of chain lengths C
