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

Jawless vertebrates (cyclostomes) have an alternative adaptive immune system in which lymphocytes somatically diversify their variable lymphocyte receptors (VLR) through recombinatorial use of leucine-rich repeat cassettes during VLR gene assembly. Three types of these anticipatory receptors in lampreys (VLRA, VLRB, and VLRC) are expressed by separate lymphocyte lineages. However, only two VLR genes (VLRA and VLRB) have been found in hagfish. Here we have identified a third hagfish VLR, which undergoes somatic assembly to generate sufficient diversity to encode a large repertoire of anticipatory receptors. Sequence analysis, structural comparison, and phylogenetic analysis indicate that the unique hagfish VLR is the counterpart of lamprey VLRA and the previously identified hagfish "VLRA" is the lamprey VLRC counterpart. The demonstration of three orthologous VLR genes in both lampreys and hagfish suggests that this anticipatory receptor system evolved in a common ancestor of the two cyclostome lineages around 480 Mya.
