1 · What the graph read from it

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.

2 · The registry

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

The present study investigated whether bromine could be replaced with its bioisostere, ethynyl group, without losing potency and selectivity toward fungi, and has found that the bioisosteric replacement strategy is successfully applied to the design, synthesis and SAR study of novel 2nd-generation N'-(salicylidene)arenecarbohydrazides, bearing ethynyl groups. This study particularly focused on the broad-spectrum antifungal activities against three critical priority fungal pathogens, C. neoformans, C. albicans, and A. fumigatus to select highly promising lead compounds. Reliable QSAR models for optimization and further drug development have been successfully created using the AutoQSAR program. Also, in silico ADME/Tox predictions were performed, which predicted considerably improved ClogP values (3.26-5.66), no mutagenicity (AMES test) except for 2 compounds (with low confidence) out of 31, no hERG toxicity, no lethal toxicity (LD
