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

Protein kinases constitute a large family of regulatory enzymes, each with a distinct specificity to restrict its action to its physiological target(s) only. The catalytic (C) subunit of protein kinase A, regarded as a structural prototype for this family, is composed of a conserved core flanked by two nonconserved segments at the amino and carboxyl termini. Here we summarize evidence to show that (i) the active site consists of an extended network of interactions that weave together both domains of the core as well as both segments that flank the core; (ii) the opening and closing of the active site cleft, including the dynamic and coordinated movement of the carboxyl terminal tail, contributes directly to substrate recognition and catalysis; and (iii) in addition to peptide and ATP, the active site contains six structured water molecules that constitute a conserved structural element of the active site. One of these active-site conserved water molecules is locked into place by its interactions with the nucleotide, the peptide substrate/inhibitor, the small and large domains of the conserved core, and Tyr-330 from the carboxyl-terminal "tail."
