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

l-Leucine aminopeptidases (LAPs) are implicated in the progress of many pathological disorders and play some regulatory roles in tumor cell proliferation, invasion, and/or angiogenesis. Thus, LAPs not only could become new diagnostic or prognostic biomarkers but also may have potential as novel molecular targets for the treatment of several cancers. Highly sensitive assays are critical for early detection of changes in LAP activity and for screening potent LAP inhibitors. In this study, we developed a novel and highly sensitive fluorescent assay for LAPs based on substituted aminopyridines as fluorescent reporters. This assay was at least 100- and 20-fold more sensitive than commercial colorimetric and fluorescent LAP substrates, respectively. We also showed that this assay was a useful tool for monitoring LAP activities in extracts from cancer cell lines, as well as for the high-throughput screening of inhibitors, which could lead to new cancer treatments.
