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

Triosephosphate Isomerase deficiency (TPI-Df) is a devastating untreatable childhood metabolic disease resulting in anemia, severe locomotor impairment, and premature death. Numerous single amino acid substitutions in TPI are pathogenic and result in rapidly progressing multisystem disease. Importantly, all known pathogenic TPI-Df mutations result in a protein that retains function, and pathogenesis is known to result from decreased steady state levels of the functioning protein. There are no small molecule therapies for TPI-Df; current treatments are limited to symptomatic support and dietary interventions. We reasoned that a phenotypic screen was most appropriate to capture agents that stabilize mutant TPI and developed a human cellular TPI-Df assay based on a cellular model of the "common" TPI
