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

This study sought to investigate the effect of calorie restriction (CR) on skeletal muscle sphingolipid metabolism and its contribution to improved insulin action in rats after a 6-month feeding study. Twenty nine (29) male Fischer 344 rats were randomized to an ad libitum (AL) diet or 30% CR. Dietary intake, body weight and insulin sensitivity were monitored. After 6 months, skeletal muscle (vastus lateralis) was obtained for insulin signaling and lipid profiling. CR significantly decreased insulin and glucose levels and also altered the expression and activity of proteins involved in sphingolipid formation and metabolism. The quantities of ceramides significantly increased in CR animals (P<.05; n=14-15), while ceramide metabolism products (i.e., glycosphingolipids: hexosylceramides and lactosylceramides) significantly decreased (P<.05; n=14-15). Ceramide phosphates, sphingomyelins, sphingosine and sphingosine phosphate were not significantly different between AL and CR groups (P=ns; n=14-15). Lactosylceramide quantities correlated significantly with surrogate markers of insulin resistance (homeostasis model of assessment on insulin resistance) (r=0.7; P<.005). Products of ceramide metabolism (glycosphingolipids), known to interfere with insulin signaling at elevated levels, were significantly reduced in the skeletal muscle of CR animals. The increase in insulin sensitivity is associated with glycosphingolipid levels.
