Design, synthesis and microbiological evaluation of ampicillin-tetramic acid hybrid antibiotics.
Article in The Journal of antibiotics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Exploiting iron-uptake pathways by conjugating β-lactam antibiotics with iron-chelators, such as catechol and hydroxamic acid is a proven strategy to overcome permeability-related resistance in Gram-negative bacteria. As naturally occurring iron-chelating tetramic acids have not been previously examined for this purpose, an exploratory series of novel ampicillin-tetramic acid hybrids that structurally resemble ureidopenicillins was designed and synthesized. The new analogs were evaluated for the ability to chelate iron and their MIC activities determined against a representative panel of clinically significant bacterial pathogens. The tetramic acid β-lactam hybrids demonstrated a high affinity to iron in the order of 10
