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

Three new Co(II) (1), Ni(II) (2), and Cu(II) (3) binuclear complexes with versatile azide bridges and Schiff base derived from 2-hydroxy-1-naphthaldehyde and 2-aminothiophenol have been synthesized. Compounds 1-3 were characterized using various techniques, including microanalysis (CHNS), molar conductance, FTIR, UV-visible, 1H-NMR, mass spec, photoluminescence (PL) spectroscopy, thermogravimetric analysis (TGA-DTG), scanning electron microscopy (SEM) and Energy dispersive X-ray (EDX) techniques. Molar conductance values of the newly synthesized complexes indicate that the complexes are electrolytes in solution. Spectroscopic results suggest that the Schiff base acts as a tridentate ligand, bonding to the metal using imino nitrogen, thiol sulphur, and hydroxy oxygen atoms. Upon the incorporation of the azide pseudohalide, the µ -1, 1 bridge are proposed for all the complexes. Electronic spectra of 1-3 suggest an octahedral environment around the metal ions. Schiff base exhibited fluorescence originating from intra-ligand (
