Diurnal temperature range and hospital admission due to cardiovascular diseases: A systematic review and meta-analysis study.
Review in International journal of cardiology. Cardiovascular risk and prevention, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
This study investigated the impact of the diurnal temperature range (DTR) on hospitalizations related to cardiovascular disease (CVD). Following the PRISMA protocol, a systematic review and meta-analysis searched various databases for English studies using keywords related to DTR and CVD up to June 1, 2023. A random-effects meta-analysis model was utilized to aggregate previous estimates of DTR effects on CVD admissions. The findings revealed that a 1 °C increase in DTR is associated with a 1.5 % increase in all CVD hospitalizations (95 % CI: 0.2 %, 3 %). Additionally, for each 1 °C increase in DTR, admissions due to acute myocardial infarction (AMI) and heart failure increased by relative risks (RR) of 1.02 (95 % CI: 1.01, 1.03) and 1.04 (95 % CI: 1.03, 1.04), respectively. Our analysis showed that a 1 °C increase in DTR was associated with a 0.9 % increase in all CVD hospital admissions among those aged ≥65 years (95 % CI: 0.3 %, 1.6 %). The overall estimates indicated that DTR (per 1 °C increment) was associated with a 0.6 % (95 % CI: 0.2 %, 1.1 %) increase in females and a 1.7 % (95 % CI: 1.3 %, 2.2 %) increase in males. It was statistically significant for elderly individuals, corresponding to a 4.5 % increase in stroke risk (RR: 1.045 [95 % CI: 1.01, 1.07]). Overall, this study emphasizes that daily fluctuations in DTR increase the hospitalization risk in cardiovascular patients, highlighting the need to consider the effects of DTR on cardiovascular health, especially among vulnerable age and sex groups.
