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
The DNA-repair enzyme endonuclease IV from the thermophilic bacterium Thermotoga maritima MSB8 (reference sequence NC_000853) has been expressed in Escherichia coli and crystallized for X-ray analysis. T. maritima endonuclease IV is a 287-amino-acid protein with 32% sequence identity to E. coli endonuclease IV. The protein was purified to homogeneity and was crystallized using the sitting-drop vapor-diffusion method. The protein crystallized in space group P6(1), with one biological molecule in the asymmetric unit, corresponding to a Matthews coefficient of 2.39 A(3) Da(-1) and 47% solvent content. The unit-cell parameters of the crystals were a = b = 123.2, c = 35.6 A. Microseeding and further optimization yielded crystals with an X-ray diffraction limit of 2.36 A. A single 70 degrees data set was collected and processed, resulting in an overall R(merge) and a completeness of 9.5% and 99.3%, respectively.
