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

Heterozygous familial hypercholesterolemia (heFH) affects 1 in 500 individuals. Evidence supports the low-density lipoprotein (LDL)-lowering effect of statins for adults with heFH. However, there are concerns regarding the treatment children with heFH. By performing a systematic review and metaanalysis of the published literature, this study aimed to evaluate the efficacy and safety of statins used for children with heFH. A systematic review was performed by searching multiple medical databases and citations to identify reports of randomized controlled trials of statins used to treat children with heFH. The trials were retrieved, reviewed, and subjected to metaanalysis. The search yielded 2,174 titles. Of the 63 studies retrieved and reviewed, 56 were excluded, 7 were included in the systematic review, and 4 were included in the metaanalysis. Significant heterogeneity was detected. The metaanalysis showed significant LDL lowering, high-density lipoprotein (HDL) cholesterol elevation, and increases in height and weight with statins. The metaanalysis could not be performed for many side effects of statins, but individual trials showed no significant side effects. Quality assessment showed methodologic concerns, with potential for bias. For example, six trials analyzed statin effects without intention to treat despite such a stated intention. Metaanalysis shows significant LDL lowering with statin treatment. Further studies, including epidemiologic and multicenter studies, are required.
