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

Background: Although carnitine supplementation has been studied for its effects on serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in patients, research in physically inactive overweight and obese individuals remains limited. Aim: This study examined the effects of L-carnitine supplementation and moderate-intensity exercise (30 min of brisk walking and interval training) on kidney and liver functions in overweight and obese individuals. Methods: Sixty-eight overweight and obese participants (29.03 ± 6.02 years) were randomly assigned to four groups: Control (C), L-carnitine supplementation alone (S), exercise alone (E), and combined L-carnitine supplement and exercise (SE). The S and SE groups consumed 1000 mg of L-carnitine daily for 12 weeks, while the E and SE groups performed 30 min of brisk walking and interval training. The control group maintained their usual routines. Kidney and liver function markers, including ALT, AST, creatinine, urea, and total bilirubin, were analyzed. Repeated measure analysis of variance (ANOVA) and post hoc Bonferroni test were used for statistical analysis. Results: No significant changes in kidney and liver function markers were observed among the groups. Conclusions: L-carnitine supplementation alone, exercise alone, and their combination do not adversely affect kidney and liver function in overweight and obese individuals, supporting their safety. Although no significant biomarker changes were detected, these findings encourage further research on long-term effects, varying exercise intensities and higher L-carnitine doses to explore potential metabolic benefits.
