Abstract

To convert the values for low-density lipoprotein (LDL) cholesterol to millimoles per liter, multiply by 0.02586.† Included in this category is the number of patients who underwent randomization and received at least one dose of a study drug.‡ Patients who were enrolled in phase 2 parent trials and who agreed to participate in the extension study were enrolled in OSLER-1.§ Patients who were enrolled in phase 3 parent trials and who agreed to participate in the extension study were enrolled in OSLER-2.

  • One PCSK9 antibody showed benefit only among patients with a baseline LDL cholesterol level of at least 100 mg per deciliter.

    “with one agent showing benefit only among patients who had a baseline LDL cholesterol level of at least 100 mg per deciliter (2.6 mmol per liter). 12”

    From Alirocumab and Cardiovascular Outcomes after Acute Coronary Syndrome (2018) · cites this paper as [12]

    The Cardiovascular Events section reports a lower event rate with evolocumab than with standard therapy in the overall study population. It does not report that benefit was limited to patients whose baseline LDL cholesterol was at least 100 mg/dl; the 100-mg/dl thresholds in the End Points table describe eligibility for some parent trials, not a cardiovascular-benefit subgroup. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Both the current trial and the SPIRE trial showed a more prominent absolute reduction in the risk of cardiovascular outcomes with PCSK9 inhibition among patients with a baseline LDL cholesterol level of 100 mg/dL or more.

    “Both our trial and the SPIRE trial showed a more prominent absolute reduction in the risk of cardiovascular outcomes with PCSK9 inhibition among patients who had a baseline LDL cholesterol level of 100 mg or more per deciliter. 12”

    From Alirocumab and Cardiovascular Outcomes after Acute Coronary Syndrome (2018) · cites this paper as [12]

    The Results (page unavailable) report a lower overall cardiovascular-event rate with evolocumab than with standard therapy, but do not report a greater absolute reduction among patients with baseline LDL cholesterol of at least 100 mg/dL. The Discussion (page unavailable) describes the SPIRE outcomes trials as still in progress, so this paper does not establish the claimed SPIRE finding. (LLM, conf=0.89)

    Experimental — accuracy not yet measured
  • In initial trials of PCSK9 inhibitors, the incidence of neurocognitive adverse events was very low (<1%) but slightly higher albeit non-significantly in the treated groups compared with placebo (0.9% vs. 0.3% for evolocumab; 1.2% vs. 0.5% for alirocumab).

    “In the initial trials of these drugs, the incidence of neurocognitive adverse events (including delirium, cognitive and attentional disturbances, dementia, thought and perceptual disturbances, and psychiatric disorders) was very low (<1%) but slightly higher albeit non-significantly in the treated groups compared with placebo (0.9% vs. 0.3% for evolocumab) (81) (1.2% vs. 0.5% for alirocumab) (82).”

    From PCSK9 and the nervous system: a no-brainer? (2023) · cites this paper as [82]

    Table 3 in the Discussion reports neurocognitive events in 27 evolocumab patients (0.9%) and 4 comparator patients (0.3%); the Safety and Side-Effect Profile also describes the rate as below 1% and higher with evolocumab. The comparator was standard therapy, not placebo. The cited passages do not establish that the between-group difference was statistically non-significant; the Results’ statement about non-significance concerns differences by achieved LDL-cholesterol level. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • There were little more than 100 events in the phase 2 and phase 3 trials of PCSK9 inhibitors combined.

    “However, there were little more than 100 events in these studies combined.”

    From Evolocumab and Clinical Outcomes in Patients with Cardiovascular Disease (2017) · cites this paper as [9]

    The Results passage reproduced in the Discussion reports 29 cardiovascular events in the evolocumab group and 31 in the standard-therapy group—60 in the combined OSLER trials. The paper identifies these as follow-up trials for participants from phase 2 and phase 3 studies, but it does not establish the claimed total of little more than 100 events across the studies referred to by the citing sentence. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Monoclonal antibodies to PCSK9 produce substantial reductions in LDL cholesterol when administered alone or with a statin.

    “These findings have led to the development of monoclonal antibodies to PCSK9 that produce substantial reductions in LDL cholesterol when administered alone or with a statin. 8-12”

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.
