Article in Acta crystallographica. Section E, Structure reports online, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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 salt, 2C19H23FN3O3 (+)·C2O4 (2-) {systematic name: bis-[4-(3-carb-oxy-1-cyclo-propyl-6-fluoro-4-oxo-1,4-di-hydro-quino-lin-7-yl)-1-ethyl-piperazin-1-ium] oxalate}, crystallizes with two independent monocations (A and B) and an oxalate dianion (C) in the asymmetric unit. The piperazinium ring in both the cations adopts a slightly disordered chair conformation. The dihedral angles between the mean planes of the cyclo-propyl ring and the 10-membered quinoline ring are 50.6 (5)° (A) and 62.2 (5)° (B). In each of the cations, a single O-H⋯O intra-molecular hydrogen bond is observed. In the crystal, the oxalate anions inter-act with the cations through N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, forming R 2 (2)(8) graph-set ring motifs. Weak C-H⋯F inter-actions along with further C-H⋯O inter-actions are observed between the cations, forming zigzag chains along [001]. In addition, π-π stacking inter-actions are observed with centroid-centroid distances of 3.5089 (13), 3.5583 (13), 3.7900 (13) and 3.7991 (13) Å.
