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
backgroundThe Dietary Index for Gut Microbiota (DI-GM) is a dietary quality indicator of gut health, weekend warrior (WW) has grown increasingly prevalent in today’s fast-paced lifestyle. The association of DI-GM and WW with mortality in hypertensive populations is currently unclear. This study aimed to explore the independent and joint associations of DI-GM and WW physical activity pattern with mortality among hypertensive patients.
methodsUtilizing data from 9082 hypertensive patients in the NHANES 2007–2018. The WW physical activity pattern was assessed using the self-reported Global Physical Activity Questionnaire, and DI-GM was estimated based on 24-hour dietary recalls. Kaplan–Meier (KM) curves and the Cox proportional hazard model were used to evaluate the associations between independent and joint prognostic effects of DI-GM and WW with mortality among hypertensive patients.
resultsDuring a median follow-up of 6.8 years, 919 deaths were recorded. Analysis showed that DI-GM was associated with all-cause mortality in hypertensive patients (HR = 0.94, 95% CI [0.90, 0.99]). The all-cause (HR = 0.59, 95%CI 0.47 to 0.74) and cardiovascular disease (CVD) mortality (HR = 0.51, 95%CI 0.33 to 0.79) were significantly lower for weekend warriors compared with inactive individuals. The combined analysis demonstrated that, compared to individuals with low DI-GM and inactivity, those with high DI-GM and WW had a 55% lower risk of all-cause mortality, while those with low DI-GM and WW exhibited a 47% reduced risk of CVD mortality.
conclusionsDI-GM demonstrated a significant inverse association with all-cause mortality risk among hypertensive patients. WW had similar benefits for all-cause mortality as regularly active. Our study revealed that the combination of high DI-GM diets with WW was robustly associated with reduced all-cause mortality risk in hypertensive patients.
