SHP family protein tyrosine phosphatases adopt canonical active-site conformations in the apo and phosphate-bound states.
Article in Protein and peptide letters, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Protein tyrosine phosphatase (PTP) catalytic domains undergo a series of conformational changes in order to mediate dephosphorylation of their tyrosine phosphorylated substrates. An important conformational change occurs in the Tryptophan-Proline-Aspartic acid (WPD) loop, which contains the conserved catalytic aspartate. Upon substrate binding, the WPD loop transitions from the 'open' to the 'closed' state, thus allowing optimal positioning of the catalytic aspartate for substrate dephosphorylation. The dynamics of WPD loop conformational changes have previously been studied for PTP1B, HePTP, and the bacterial phosphatase YopH, but have not yet been comprehensively studied for the nonreceptor tyrosine phosphatase SHP-1 (PTPN6). To structurally describe the changes in WPD loop conformation in SHP-1, we have determined the 1.4 Å crystal structure of the catalytic domain of SHP-1 in the Apo state and the 1.8 Å crystal structure of the SHP-1 catalytic domain in complex with a phosphate ion. We provide structural analysis for the WPD loop closed state of SHP phosphatases and the conformational changes that occur upon WPD loop closure.
