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

contextDyslipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD), and curcumin may help improve lipid metabolism.

objectiveThis umbrella review and updated meta-analysis assessed the effects of curcumin supplementation on lipid profiles. DATA SOURCES: Electronic databases (Medline, Scopus, Cochrane, and Google Scholar) were searched through March 31, 2023, without language restrictions. DATA EXTRACTION: Two independent authors selected eligible randomized controlled trials (RCTs) involving curcumin supplementation compared with placebo, measuring total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-c), high-density-lipoprotein cholesterol (HDL-c), and triglyceride (TG) levels. DATA ANALYSIS: This study identified 26 systematic reviews and meta-analyses (MAs) that met the inclusion criteria for the umbrella review. Of these, 53 RCTs, with a corrected coverage area of 9.76% indicating a moderate degree of overlap, were included for re-pooling. Additionally, this study found 19 more RCTs, bringing the total number of studies for the updated MAs to 72.

resultsCurcumin significantly reduced TC, LDL-c, and TG, with mean differences (MDs) of -7.76 mg/dL (95% CI: -11.29, -4.22; I2 = 97%), -5.84 mg/dL (95% CI: -11.63, -0.05; I2 = 98%), and -13.15 mg/dL (95% CI: -17.31, -8.98; I2 = 94%), respectively, and increased HDL-c by 2.4 mg/dL (95% CI: 1.22, 3.57; I2 = 94%). The reductions in LDL-c and TG reached the minimally clinically important differences (MCIDs). However, the reduction in TC and increase in HDL-c did not meet their respective MCIDs. Subgroup analysis showed greater lipid improvements in patients with metabolic-related diseases, particularly type 2 diabetes. Enhanced bioavailability forms of curcumin, supplementation for at least 8 weeks, and exercise yielded additional benefits.

conclusionThe study confirmed that curcumin has an anti-lipidemic effect on patients with noncommunicable diseases. A form of curcumin with enhanced bioavailability is preferred, and supplementation for at least 8 weeks, along with exercise, may be used as an accessible approach to reduce the risk of ASCVD.
