Abstract

Mild-to-moderate AD patients were randomized to placebo or rosiglitazone (RSG) 2, 4 or 8 mg. Primary end points at Week 24 were mean change from baseline in AD Assessment Scale-Cognitive (ADAS-Cog) and Clinician's Interview-Based Impression of Change Plus Caregiver Input global scores in the intention-to-treat population (N=511), and results were also stratified by apolipoprotein E (APOE) genotype (n=323). No statistically significant differences on primary end points were detected between placebo and any RSG dose. There was a significant interaction between APOE epsilon4 allele status and ADAS-Cog (P=0.014). Exploratory analyses demonstrated significant improvement in ADAS-Cog in APOE epsilon4-negative patients on 8 mg RSG (P=0.024; not corrected for multiplicity). APOE epsilon4-positive patients did not show improvement and showed a decline at the lowest RSG dose (P=0.012; not corrected for multiplicity). Exploratory analyses suggested that APOE epsilon4 non-carriers exhibited cognitive and functional improvement in response to RSG, whereas APOE epsilon4 allele carriers showed no improvement and some decline was noted. These preliminary findings require confirmation in appropriate clinical studies.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Thiazolidinediones (PPAR-gamma agonists) are powerful insulin sensitizers effective in lowering insulin resistance and preventing type 2 diabetes, with efficacy similar to lifestyle strategies and greater than metformin.

    “Among the pharmacologic strategies, the thiazolidenidiones, also known as PPAR-gamma agonists, are powerful insulin sensitizers effective in lowering insulin resistance [66] and preventing T2D [67], with efficacy similar to lifestyle strategies and greater than metformin [68].”
  • One trial found rosiglitazone was effective in memory and attention, but another randomized placebo controlled trial and a Phase III trial failed to demonstrate its effectiveness in cognitive function.

    “One trial found rosiglitazone was effective in memory and attention (18) but another randomized placebo controlled trial and a Phase III trial failed to demonstrate its effectiveness in cognitive function (19,20).”
  • Trials have failed to demonstrate thiazolidinedione effectiveness in dementia patients' cognitive function, probably due to adverse cardiovascular effects outweighing potential benefits.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
