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
Rv0864 (MoaC2) from Mycobacterium tuberculosis is one of the enzymes in the molybdenum cofactor (Moco) biosynthesis pathway. Together with MoaA, MoaC is involved in the conversion of guanosine triphosphate (GTP) to precursor Z, the first step in Moco synthesis. Full-length MoaC2 (17.5 kDa, 167 residues) was cloned in Escherichia coli and purified to homogeneity. Crystals of recombinant M. tuberculosis MoaC2 were grown by vapour diffusion using a hanging-drop setup. Diffracting crystals grew in a condition in which 3 µl protein solution at 10.5 mg ml(-1) was mixed with 1.5 µl reservoir solution (0.025 M potassium sodium tartrate tetrahydrate pH 8.0) and equilibrated against 1000 µl reservoir solution. Diffraction data extending to 2.5 Å resolution were collected at 100 K. The crystal belonged to the cubic space group P2(1)3, with unit-cell parameter 94.5 Å. Matthews coefficient (V(M)) calculations suggested the presence of two molecules in the asymmetric unit, corresponding to a solvent content of about 39%. Molecular-replacement calculations using the E. coli homologue as the search model gave an unambiguous solution.
