Abstract

Hypercholesterolaemia is directly associated with an increased risk for coronary heart disease and other sequelae of atherosclerosis. Artichoke leaf extract (ALE) has been implicated in lowering cholesterol levels. Whether ALE is truly effective for this indication is still a matter of debate. This is an update of a review first published in 2002 and last updated in 2009. To assess the efficacy and safety of ALE in the treatment of hypercholesterolaemia. We updated searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library) (2012, Issue 5); MEDLINE Ovid (1966 to May Week 2, 2012); EMBASE Ovid (1980 to 2012 Week 19); and CINAHL Ebsco (1982 to May 2012) on 17 May 2012. CISCOM was last searched until June 2001, and AMED until June 2008. We checked reference lists of articles, and contacted manufacturers of preparations containing artichoke extract, and experts on the subject. No language restrictions were applied. We included randomised controlled trials (RCTs) of ALE mono-preparations compared with placebo or reference medication for patients with hypercholesterolaemia. We excluded trials assessing ALE as one of several active components in a combination preparation or as a part of a combination treatment. Data were extracted systematically and risk of bias was evaluated using the Cochrane 'Risk of bias' tool. Two authors independently performed the screening of studies, selection, data extraction and assessment of risk of bias. Disagreements in the evaluation of individual trials were resolved through discussion. We included three RCTs involving 262 participants. The trials were of adequate methodological quality but had some shortcomings. One trial was at low quality of risk, one at medium and one of unclear risk of bias. One trial is available as abstract only and includes a small sample. In the first trial the total cholesterol level in participants receiving ALE decreased by 4.2% from 7.16 (0.62) mmol/L to 6.86 (0.68) mmol/L after 12 weeks, and increased from 6.90 (0.49) mmol/L to 7.04 (0.61) mmol/L in patients receiving placebo, the total difference being statistically significant (P = 0.025). In the second trial ALE reduced total cholesterol levels by 18.5% from 7.74 mmol/L to 6.31 mmol/L after 42 ± 3 days of treatment, whereas placebo reduced cholesterol by 8.6% from 7.69 mmol/L to 7.03 mmol/L (P = 0.00001). The third trial, which is available as abstract only and provides limited data, stated that ALE significantly reduced blood cholesterol compared with placebo in a subgroup of patients with baseline total cholesterol levels of more than 230 mg/dL (P < 0.05). Trial reports indicate mild, transient and infrequent adverse events. Data from three clinical trials assessing ALE for treating hypercholesterolaemia are available. Athough the trials are of adequate methodological quality they have some shortcomings and one is available as abstract only. There is an indication that ALE has potential in lowering cholesterol levels, but the evidence is, as yet, not convincing. The limited data on safety suggest only mild, transient and infrequent adverse events with the short term use of ALE.

Attention Score in Context

This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 January 2017.
All research outputs
#1,403,684
of 12,527,219 outputs
Outputs from Cochrane database of systematic reviews
#3,854
of 8,923 outputs
Outputs of similar age
#41,358
of 261,548 outputs
Outputs of similar age from Cochrane database of systematic reviews
#57
of 131 outputs
Altmetric has tracked 12,527,219 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 8,923 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 21.2. This one has gotten more attention than average, scoring higher than 66% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 261,548 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 84% of its contemporaries.
We're also able to compare this research output to 131 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
