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

objectivesDiverse analysis has analyzed the potential efficacy of consuming foods created through the fermentation of dairy in mitigating abdominal obesity. The current meta-analysis aims to determine the impacts of consuming fermented dairy foods and the occurrence of abdominal obesity.

methodsWeb of Science, PubMed, and Scopus databases were queried for records published before January 13, 2023, to investigate proportionate cohort studies. We employed a random-effects model to appraise the relative risk (RR); effect size was assessed through the 95% confidence interval (CI). Additionally, a one-stage dose-response analysis was executed, quality assessment was conducted through the ROBINS-E tool.

resultsConsequently, five publications, comprising 41,430 cases, were included as selected studies. The pooled effect shows an effect on the abdominal obesity risk; however, the effect was not significant. Subgroup analyses revealed a potential risk reduction effect in high- and low-fat and fermented dairy productions, although the findings were not statistically significant. Furthermore, the dose-response analysis indicated a linear decrease in risk with increasing consumption of high-fat fermented yogurt, with an HR of 0.84 (95% CI 0.71, 0.99) by 8 servings/week and an HR of 0.37 (95% CI 0.19, 0.71) by 21 servings/week.

conclusionThese findings imply the potential effectiveness of fermented dairy products, particularly high-fat yogurt, in diminishing the obesity risk. However, further research addressing the limitations of previous studies is essential to confirm these results. Evidence-based medicine level: No level of evidence: Level of evidence III.
