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 NELL2-interacting cofactor for lumicrine signaling (NICOL) is a small protein which forms a complex with the neural epidermal growth factor-like like 2 (NELL2) and engaged in sperm maturation in the epididymis. At present, the recombinant expression of NICOL is not efficient, which limits the precise understanding of the structure and function of NICOL. In this study, we first succeeded in the chemical synthesis of NICOL with NELL2 binding affinity. The synthesized NICOL possesses correct SS bond pairing, and its secondary structure is indistinguishable from that of the recombinant protein, indicating that the synthetic NICOL will be useful for structural and functional analyses of lumicrine signaling.
