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

Lysosomes are critical for maintaining protein homeostasis and cellular metabolism. Lysosomal dysfunction and disrupted protein trafficking contribute to cell death in neurodegenerative disorders, including Parkinson's disease and dementia. We describe three complementary protocols-the use of protein glycosylation, western blotting, immunofluorescence, and hydrolase activity measurement-to analyze the trafficking and activity of lysosomal proteins in patient-derived neurons differentiated from iPSCs. These methods should help to identify lysosomal phenotypes in patient-derived cultures and aid the discovery of therapeutics that augment lysosomal function. For complete details on the use and execution of this protocol, please refer to Cuddy et al. (2019).
