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

In a 1998 collaboration with Tony Fink, we coupled nanosecond circular dichroism methods (TRCD) with a CO-photolysis system for quickly triggering folding in cytochrome c (cyt c) in order to make the first time-resolved far-UV CD measurement of early secondary structure formation in a protein. The small signal observed in that initial study, approximately 10% of native helicity, became the seed for increasingly robust results from subsequent studies bringing additional natural and magnetic circular polarization dichroism and optical rotatory dispersion detection methods (e.g., TRORD, TRMCD, and TRMORD), coupled to fast photolysis and photoreduction triggers, to the study of early folding events. Nanosecond polarization methods are reviewed here in the context of the range of initiation methods and structure-sensitive probes currently available for fast folding studies. We also review the impact of experimental results from fast polarization studies on questions in folding dynamics such as the possibility of multiple folding pathways implied by energy landscape models, the sequence dependence of ultrafast helix formation, and the simultaneity of chain collapse and secondary structure formation implicit in molten globule models for kinetic folding intermediates.
