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

The retinocollicular projection is a preferred axon guidance pathway for investigating molecular mechanisms of synaptic targeting in the mammalian CNS. Here we identify a previously unrecognized role of the L1 cell adhesion molecule in topographic mapping of retinal ganglion cell (RGC) axons to their targets in the mouse superior colliculus (SC). L1 was transiently expressed on RGC axons during axon growth and targeting. DiI labeling of retinal axons revealed that temporal axons of L1-minus mice bypassed correct target locations in the anterior SC, forming termination zones at incorrect posterior sites, which were often skewed along the mediolateral axis. During development of the retinotopic map L1-minus temporal axons extended across the anteroposterior axis of the SC like wild-type axons but failed to arborize at normal anterior target sites. L1-minus RGC axons exhibited normal crossing at the optic chiasm and fasciculation of the optic nerve. Results suggest that retinal axons require the function of L1 in addition to repellent EphA guidance receptors to achieve proper topographic mapping.
