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 asymmetric unit of the title compound, C19H16N2O5S, contains four independent mol-ecules (A, B, C and D), with two mol-ecules (B and D) displaying disorder in their methyl-sulfanyl groups [occupancy ratios of 0.797 (11):0.203 (11) and 0.85 (2):0.15 (2)]. The nitro groups are twisted slightly out of the planes of the 2-pyrroline rings to which they are bonded with dihedral angles of 10.17 (1), 8.01 (1), 9.44 (1) and 8.87 (1)° in mol-ecules A, B, C and D, respectively. The 2-pyrroline rings are almost orthogonal to the attached tolyl rings, forming dihedral angles of 73.44 (1), 81.21 (1), 88.18 (8) and 73.94 (1)° for mol-ecules A, B, C and D, respectively. A weak intra-molecular O-H⋯O inter-action is observed in mol-ecules B and C. The two hy-droxy groups in each mol-ecule are involved in inter-molecular O-H⋯O hydrogen bonding. In the crystal, mol-ecules are connected via O-H⋯O and C-H⋯O hydrogen bonds, forming a complex three-dimensional network.
