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

introductionOne of the most common chronic diseases is obesity. Disturbances in circadian rhythm and sleep quality are common in these people. Genes related to circadian rhythm control are also disrupted. One of the methods of controlling and reducing obesity is to intervene in the individual's diet, and one of the alternative methods to the conventional low-calorie diet is the use of fasting diets, including time-restricted eating (TRE), which can have effects on the expression of a circadian rhythm genes, the circadian rhythm status, and the quality of sleep. This randomized controlled trial (RCT) will be aimed to examine the effect of the TRE diet in comparison with an energy-restricted diet (ERD) on the expression of basic helix-loop-helix ARNT-Like-1 (BMAL-1) and micro ribonucleic acid (miRNA)-let-7f-1-3p genes, circadian rhythm status, and sleep quality in women with obesity. METHODS AND ANALYSIS: This study will be conducted on 42 obese women. Participants will be randomly assigned to receive either 16:8 TRE (fasting from 8 to 12 PM the next day) or an ERD (55% carbohydrate, 30% fat, 15% protein) diet for 12 weeks. Gene expression, circadian rhythm status, sleep quality, anthropometric measurements, and metabolic evaluations will be assessed before and after the intervention. Dietary evaluations will be performed at baseline, middle, and end of the study. DISCUSSION: Since circadian rhythm-related gene expression has a role in circadian rhythm and ultimately obesity regulation, it seems that TRE, as a dietary approach, can affect these gene expressions.
