Joint Effect of Central Obesity and Family History on Hypertension in Type 2 Diabetes: A Cross-Sectional Study in China.

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.
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
Purpose: This study aimed to examine the joint effect of central obesity (CO) and family history of hypertension (FHH) on hypertension in Chinese patients with type 2 diabetes mellitus (T2DM). Methods: A total of 1756 T2DM patients were enrolled from a cross-sectional study conducted in Zhejiang Province, China (March - November 2018). Multivariate logistic regression models were used to analyze factors associated with hypertension and to assess CO-FHH interactions on both additive and multiplicative scales. Associations between waist circumference (WC) and systolic/diastolic blood pressure (SBP/DBP) were evaluated using generalized additive models (GAM) and Spearman correlation. The relationship between WC and hypertension was further explored using restricted cubic splines (RCS). Results: The prevalence of hypertension was 64.52%. WC was positively correlated with SBP (r = 0.25, P<0.001) and DBP (r=0.27, P<0.001), and showed a linear association with hypertension in both sexes (P for non-linearity>0.05). After adjusting for potential covariates, T2DM patients with both CO and FHH had a 4.64-fold higher risk of hypertension (95% CI: 3.22-6.67) compared to the reference group. A statistically significant additive interaction between CO and FHH was observed, with a relative excess risk due to interaction (RERI) of 1.59 (95% CI: 0.39-3.19), an attributable proportion (AP) of 0.34 (95% CI: 0.08-0.51), and a synergy index (SI) of 1.78 (95% CI: 1.13-2.79). No statistically significant multiplicative interaction was found. Conclusion: CO and FHH may jointly contribute to hypertension in Chinese T2DM patients through an additive effect beyond their individual associations. Maintaining a healthy WC is especially important for T2DM patients with a family history of hypertension.
