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
Lipoprotein (a) [Lp(a)] is a risk factor for coronary artery disease. It is characterized by apolipoprotein (a) [apo(a)] disulphide linked to apolipoprotein B (apoB), by Cys4057 of apo(a) and possibly Cys3734 of apoB. We call this the covalent apo(a):apoB-Lp interaction, to distinguish it from the non-covalent Lp(a):apoB-Lp interaction, mediated by the proline-binding kringle-4-like domain(s) of Lp(a). The Lp(a):apoB-Lp interaction was inhibited by an apoB peptide spanning residues 3304-3317. This peptide was found by a computerized search for sites on apoB similar to the plasminogen's kringle-4-binding site of alpha 2-antiplasmin. It probably constitutes part of the Lp(a)-binding site on apoB because: (1) it corresponds to the alpha 2-antiplasmin minimum binding domain for plasminogen's kringle-4; (2) the competitive nature of inhibition [KI = (1.5 +/- 0.7) x 10(-4) M, n = 5] suggested that it and apoB-Lp bound to Lp(a) by the same mechanism at the same site; and (3) it specifically bound Lp(a) and not apoB-Lp, and the bound Lp(a) was dissociated by inhibitors of the Lp(a):apoB-Lp interaction, 6-aminohexanoic acid and L-proline. Inhibition was independent of its proline residue, suggesting that proline in the context of a peptide is not a ligand for the kringle(s) which mediated the binding of Lp(a) to apoB-Lp.
