Histidine is essential for growth of Komagataella phaffii cultured in YPA medium.
Article in FEBS open bio, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Komagataella phaffii (a.k.a. Pichia pastoris) requires histidine for optimal growth when cultured in a medium containing yeast extract, peptone (YP), and acetate (YPA). We demonstrate that HIS4-deficient, K. phaffii strain GS115 exhibits a growth defect on YP-media containing acetate, but not on other carbon sources. K. phaffii X33, a prototroph, grows better than K. phaffii GS115 (his4), a histidine auxotroph in YPA. Normal growth of GS115 is restored either by the expression of HIS4 or by culturing in YPA containing ≥0.6 mM histidine. In the presence of histidine, expression of several genes is altered, including those encoding key subunits of mitochondrial ATP synthase, transporters of amino acids and nutrients, as well as biosynthetic enzymes. Thus, histidine should be included as an essential component for optimal growth of K. phaffii histidine auxotrophs cultured in YPA.
