Causal relationship between oral diseases and hypertension: a Mendelian randomization study.

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
Current evidence supports the potential association between several common oral diseases and hypertension. The aim of the research is to clarify the causal relationship between these oral diseases and hypertension using Mendelian randomization (MR) analysis. Single nucleotide polymorphisms (SNPs) related to five oral traits (periodontitis, bleeding gums, loose teeth, periapical abscess and dental caries) were obtained from GWAS catalog, while those associated with hypertension (essential and secondary) were extracted from the FinnGen database. The SNPs were employed as instrumental variables (IVs) in the MR analysis. Assorted methods were applied, and inverse variance-weighted (IVW) analytical method was prioritized. Sensitivity analyses including MR-PRESSO method, MR Egger intercept test, Cochran's Q test, leave-one-out analysis and MR Steiger test were conducted. Our analysis identified the potential causal relationship between dental caries and essential hypertension. The forward MR analysis demonstrated a significant causal effect of dental caries on essential hypertension (OR = 1.036, 95%CI: 1.012-1.059,
