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

Spinocerebellar ataxia type 2 (SCA2) is a neurodegenerative disorder that shows cerebellar glucose hypometabolism, systemic hypermetabolism and weight loss. This study aimed to explore novel molecular mechanisms of disease for SCA2, based on the assessment of blood glucose homeostasis. A case-control and correlational study was conducted in 79 normoglycemic Cuban patients with SCA2 and 83 sex- and age-matched control subjects during a fasting state. A subset of 20 patients with SCA2 and 19 control individuals underwent an oral glucose tolerance test (OGTT). Several indices for assessing blood glucose homeostasis, derived from the fasting state or the OGTT, were included in the study. Fasting glucose levels showed a small increase, whereas the QUICKI index for insulin sensitivity was slightly decreased among patients. Markers of glucose homeostasis derived from the OGTT were no different between patients and controls. Fasting insulin levels, QUICKI, McAuley´s, HOMA2-%S, HOMA2-IR, and HOMA2-%β indices showed weak to moderate correlations with markers of body composition. McAuley´s, TyG, HOMA2-IR, and HOMA2-%β indices correlated with the age at onset, progression rate, or INAS count. Patients with SCA2 with mild-to-moderate ataxia do not have any major alteration in blood glucose homeostasis. Markers of glucose homeostasis associate with body composition and have nominal modifying effects on disease severity and progression rate in patients with SCA2, with McAuley's index showing effects more consistently. Further studies are needed to describe the changes in blood glucose homeostasis in the different stages of disease, and to delve into its pathophysiological relevance.
