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

Blood-feeding exoparasites are rich sources of protease inhibitors, and the mosquito Aedes aegypti, which is a vector of Dengue virus, Yellow fever virus, Chikungunya virus and Zika virus, is no exception. AaTI is a single-domain, noncanonical Kazal-type serine proteinase inhibitor from A. aegypti that recognizes both digestive trypsin-like serine proteinases and the central protease in blood clotting, thrombin, albeit with an affinity that is three orders of magnitude lower. Here, the 1.4 Å resolution crystal structure of AaTI is reported from extremely tightly packed crystals (∼22% solvent content), revealing the structural determinants for the observed inhibitory profile of this molecule.
