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 aggregation of human islet amyloid polypeptide (hIAPP) is associated with type II diabetes. The misfolding of hIAPP induces amyloid deposition and causes β-cell dysfunction. Metal complexes are potential metallodrugs that may reverse the aggregation of amyloid peptides. hIAPP19-37 is a crucial fragment of the full-length hIAPP1-37 and contains typical aromatic residues and a core hydrophobic region. In this work, we studied the effects of titanocene complexes titanocene dichloride (1), titanocene salicylic acid complex (2), and titanocene methionine complex (3) on the aggregation behavior of hIAPP19-37. We also explored the possible interactions of these complexes with hIAPP19-37. Results demonstrated that the titanocene complexes could effectively inhibit the aggregation of hIAPP19-37. The complexes bound with hIAPP19-37 in a spontaneous and exothermic process through hydrophobic interaction. Moreover, complex 3 could significantly decrease the cytotoxicity of hIAPP19-37 and improve cell survival. These data provide a basis for the use of titanocene complexes as potential agents against amyloidosis.
