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

A ring annelation reaction was used to successfully prepare benzo[4,5]imidazo[1,2-a][1,3,5]triazines (Systematic Name: 1,3,4a,9-tetraza-4H-fluoren-2-amines) tethered to phenoxy-N-arylacetamide, pyrazole, and 2-(4-(1-phenyl-1H-pyrazol-3-yl)phenoxy)-N-arylacetamide moieties utilizing 1-(1H-benzo[d]imidazol-2-yl)guanidine and the proper aldehydes as precursors. 2-(Phenylamino)ethyl fragment of compound 7 was cleaved off and compound 8 was formed. The constitutions of the novel compounds were confirmed based on spectral data. The antibacterial activity was evaluated for the prepared compounds against two gram-negative and two gram-positive bacteria. Among them, compound 12b (inhibition zone 16 ± 0.7 mm) was the most promising against S. aureus compared to Gentamycin (15 ± 0 mm). Also, compounds 5a and 5d exerted comparable antibacterial activity (inhibition zones 13 ± 1.4 and 13 ± 2.1 mm), respectively to Gentamycin against S. aureus. Minimum inhibitory concentration (MIC) evaluation against S. aureus showed that compound 12b had the lowest MIC value (78.1 µg/mL).
