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 title compound, C15H12N4O4·2H2O, crystallizes with two independent water mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the benzene and pyrimidine rings and that of the pyrimidin-4-one ring are 85.1 (9) and 82.1 (1)°, respectively. The mean plane of the pyrimidine ring is twisted by 12.8 (8)° from that of the pyrimidin-4-one ring. The dihedral angles between the benzene ring and the mean planes of the pyrimidine and pyrimidin-4-one rings are 85.1 (9) and 82.1 (1)°, respectively.In the crystal, N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds involving both water mol-ecules are present; these link the mol-ecules into a two-dimensional network parallel to (010). In addition, weak C-H⋯π and π-π [centroid-centroid distance = 3.6183 (8) Å] inter-actions occur.
