Intracellular aspartic proteinase Apr1p of Candida albicans is required for morphological transition under nitrogen-limited conditions but not for macrophage killing.
Article in Folia microbiologica, 2014. 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
Vacuolar hydrolases have been thoroughly characterized in Saccharomyces cerevisiae, but their homologues in the fungal pathogen Candida albicans have received less attention. The genes APR1 and CPY1 of C. albicans encode putative vacuolar aspartic proteinase and serine carboxypeptidase, respectively. We examined properties of apr1Δ and cpy1Δ mutants, showing that Cpy1p molecular species detected in cell lysates of apr1Δ and its parental strain did not differ in molar mass. Processing of Cpy1p precursor is apparently independent of Apr1p. This is in contrast to S. cerevisiae, where vacuolar aspartic proteinase Pep4p is known to participate in the activation of other vacuolar hydrolases including serine carboxypeptidase. We also found that both apr1Δ and cpy1Δ strains are able to form hyphae in nutrient-rich filamentation media. However, proline as a sole nitrogen source induced filamentation only in cpy1Δ and its parental strain, but not in apr1Δ. This indicates the importance of Apr1p for the morphological transition under nitrogen-limited conditions. Despite that, the ability of apr1Δ to kill murine macrophages was not reduced under the conditions tested.
