Associations between spice or pepper (Capsicum annuum) consumption and diabetes or metabolic syndrome incidence.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSpice and pepper are recognized as sources of antioxidants and anti-inflammatory compounds. This study investigated the association between spice or pepper intake and metabolic syndrome (MetS), related risk factors, or type 2 diabetes (T2D) incidences.
methodsThe qualified Tehran Lipid and Glucose Study (TLGS) participants were included. In all examinations, dietary, anthropometrical, and biochemical variables were measured. Multivariable Cox proportional hazards regression models were exploited to determine the relationship between spice or pepper consumption and the hazard ratios for Type 2 Diabetes (T2D), Metabolic Syndrome (MetS), or its components.
resultsThe analysis was performed on 5340 individuals, with a mean age of 39.9±13.4 and 406 incident cases of T2D. Also, 4353 participants were included for MetS analysis with 1211 incident cases and a median follow-up of 5.8 years. After adjusting for confounding factors, spice and pepper intakes were not associated with T2D or MetS incidence. Further, in the upper quartile of spice intake, the HRs of high triglyceride (TG) [HR Q4: 1.19 (CI: 1.05-1.35)] and high blood pressure (BP) [HR Q4: 1.16 (CI: 1.04-1.30), P-trend = 0.007] increased. The risk of HDL-C appeared to decrease in the third quartile of pepper consumption (HR: 1, 0.97, 0.87, 1.03, P-trend = 0.008).
conclusionThe findings showed that spice and pepper consumption had no association with the incidence of T2D and MetS. The risk of high TG and high BP incidence was elevated in the upper quartiles of spice intake. Also, greater consumption of pepper decreased the incidence of low HDL-C.
