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

Homozygosity for a mutation in the idi-1 gene of Caenorhabditis elegans results in paralysis during the first larval stage, followed by an arrest of growth and development late in the first larval stage. Apoptotic corpses, which are apparently the result of normal programmed cell death, persist in the arrested larvae. In genetic mosaics, an additional defect becomes evident upon examination with Nomarski optics: cells that are genotypically mutant enlarge, and their cytoplasm becomes dimpled. Electron microscopy indicates that the dimpling reflects an accumulation of many enlarged lysosomes and autophagosomes. The mosaics demonstrate that the lethal mutation acts cell autonomously with respect to this vesicular abnormality and that there is a maternal effect with respect to the time of developmental arrest of mutant progeny. Cloning of the gene reveals that it is the only gene in C. elegans for isopentenyl-diphosphate isomerase, an enzyme that is important for the synthesis of lipophilic molecules, including farnesyl and geranyl diphosphates.
