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 objective of this study was to optimize the in vivo activity of proteolipid protein (PLP)-bifunctional peptide inhibitor (BPI) molecule to suppress experimental autoimmune encephalomyelitis (EAE) in SJL/J mice and evaluate pharmacokinetic profiles of PLP-BPI. PLP-BPI is constructed via conjugation of myelin PLP(139-151) with CD11a(237-246)-derived peptide (LABL) via a spacer. The hypothesis is that PLP-BPI binds simultaneously to major histocompatibility complex-II and intercellular adhesion molecule-1 on the antigen-presenting cell (APC) and inhibits the formation of the immunological synapse during T-cell and APC interactions. In this study, the structure of BPI was modified by varying the spacer and was evaluated in the EAE model. Intravenous injections of BPI derivatives inhibited the onset, severity, and incidence of EAE more effectively and induced a lower incidence of anaphylaxis than that produced by unmodified PLP-BPI. As anticipated, production of interleukin-17, a proinflammatory cytokine commonly found in elevated levels among multiple sclerosis (MS) patients, was significantly lower in Ac-PLP-BPI-PEG6- or Ac-PLP-BPI-NH(2)-2-treated mice than in phosphate-buffered saline-treated mice. These results suggest that BPI-type molecules can be modified to achieve more efficient and better tolerated BPI-based derivatives for the treatment of MS.
