Bismuth(III) α-hydroxy carboxylates: highly selective toxicity of glycolates towards Leishmania major.

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
Eight bismuth(III) complexes derived from the simple α-hydroxycarboxylic acids; gluconic (H₆-glu), tartaric (H₄-tar), mandelic (H₂-man), malic (H₃-mal) and glycolic (H₂-gly) have been synthesised and characterised. The complexes are formed through direct treatment of the organic acids with Bi(NO₃)3·5H₂O ([Bi(H₂-tar)(H₃- tar)] 2, [Bi(mal)(NO₃)(H₂O)₂] 6, [Bi(gly)(NO₃)(H₂O)] 8) or Bi(OtBu)₃ ([Bi(H-tar)(H₂O)₂] 1, [Bi(man)(H-man) (H₂O)] 4, [Bi2(H-mal)₃] 5, [Bi(gly)(H-gly)] 7), or through metathesis of the sodium salts with Bi(NO₃)3·5H₂O ([Bi(H3-glu)]₃). Reactions with both glucuronic and mucic acid proved to be unsuccessful. Small crystals of [Bi(gly)4(NO₃)4(H₂O)₄]·5H₂O 8 were obtained from aqueous solution and analysed by synchrotron X-ray diffraction. The data were relatively poor but composition and connectivity were established, confirming and supporting other analyses. Those complexes which displayed sufficient solubility; 2, 4, 7 and 8, were tested for their anti-Leishmanial activity against parasite promastigotes and amastigotes, and for toxicity against human fibroblast cells. All four complexes and their parent acids showed no toxicity towards either the promastigotes or fibroblast cells. However, the two glycolate complexes showed selective toxicity towards amastigotes with complex 8 providing for a low % viability of 1.8 ± 0.9 at 50.0 μM. Graphical Abstract Novel bismuth(III) complexes derived from α-hydroxycarboxylic acids have been synthesised, characterised and assessed for their anti-leishmanial activity. The glycolate complexes are selectively toxic against parasite amastigotes, with all complexes being nontoxic towards promastigotes and human fibroblast cells.
