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.

Abstract

backgroundRecent evidence links diet and physical activity with type 2 diabetes mellitus (T2DM) remission, but emerging findings suggest that immune system dysregulation may play a crucial role. This study aimed to investigate the associations between neutrophils and T2DM remission.

methodsWe conducted a comprehensive analysis of newly-diagnosed T2DM patients (N = 183) from the CORDIOPREV study, without glucose-lowering treatment, and were randomized to follow either a Mediterranean or low-fat diet. Patients were classified into two groups: Responders, who achieved T2DM remission (n = 73), and Non-Responders, who did not achieve remission during the 5-year dietary intervention (n = 110). Neutrophil count and their related-ratio (NER, NBR, NLR and NHR, normalized with erythrocytes, basophils, lymphocytes, and HDL respectively) were measured at the baseline and 5 years of follow-up.

resultsThe lowest baseline tertile of neutrophil count was associated with an increased likelihood of T2DM remission among patients following a Mediterranean diet (but not for low-fat diet) when compared with the highest tertile [adjusted HR of 4.23 (95% CI: 1.53-11.69)], in which similar results were observed for NER and NHR. When considering clinical and neutrophil variables, the predictive capacity of this model yielded an AUC of 0.783 (95% CI: 0.680-0.822). Furthermore, after 5-years, Responders exhibited lower neutrophil count compared to Non-responders (p = 0.006) and a significant decrease in neutrophil count (p = 0.001) compared to baseline. This decrease in neutrophil count in Responders who consumed a Mediterranean diet exhibited a significant increase in Insulin Sensitivity and Disposition Index (p = 0.011 and p = 0.018) after the follow-up period.

conclusionThese findings suggest that neutrophil count can help in identifying patients that are more likely to achieve T2DM remission following a Mediterranean diet, suggesting a role on insulin sensitivity and β-cell function. Further research holds promise for providing valuable insights into the pathophysiology of T2DM. CLINICAL
