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

There are only a few studies on the function of neuronal axon guidance molecules during low brain pH conditions. We previously reported that roundabout (ROBO) 2, a receptor for the axon guidance molecule SLIT, can bind to the neural epidermal growth factor-like-like (NELL) ligands in acidic conditions by conformational change of its ectodomain. Here, we show that the ROBO3 receptor also exhibits a pH-dependent increase in binding to the NELL2 ligand. We found that the Glu592 residue of ROBO3 at the binding interface between NELL2 and ROBO3 is a pH sensor and that the formation of a new hydrogen bonding network, due to protonation of the Glu592, leads to increased binding in acidic conditions. These results suggest that NELL2-ROBO3 signaling could be regulated by extracellular pH.
