Unmasking the True Identity of Rapamycin's Minor Conformer.
Article in Journal of natural products, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Rapamycin, a well-known macrocyclic natural product with myriad biological activities, has been the subject of intense study since its first isolation and characterization over five decades ago. Rapamycin has been found to adopt a single conformation in the solid state (both when protein bound and uncomplexed) and exists as a mixture of two conformations in solution. Early work established that the major conformer in solution is the trans amide isomer but left the minor conformer mostly uncharacterized. Since that time, it has been widely accepted that the minor conformer of rapamycin is the cis amide, based solely on analogy to FK-506, another potent immunosuppressive compound with some shared key structural elements. To address this long-standing and unresolved question, the solution structure of the minor conformer of rapamycin was investigated using a combination of NMR techniques and computational methods and determined to be a trans amide species with rotation about the ester linkage.
