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

We have studied the light-dependent expression of the Chlamydomonas reinhardtii csbp gene encoding sedoheptulose-1,7-bisphosphatase (SBPase), an enzyme of the pentose-phosphate pathway. Expression studies using light/dark-synchronized cultures revealed that csbp mRNA abundance increases significantly during illumination. We have used a 1.4 kb region upstream of the csbp gene in transcriptional fusions to the homologous arylsulfatase-encoding reporter gene (ars). In transformants carrying the chimeric csbp/ars reporter gene, arylsulfatase activity is detected in the absence of sulfate, a condition under which the endogenous ars gene is repressed. Moreover, ars mRNA accumulation is dramatically stimulated by light, indicating that 1.4 kb of the csbp 5'-untranslated region are sufficient to confer light-dependent expression on the ars reporter gene.
