The influence of daily air temperature variability on arterial blood pressure: findings from a cross-sectional study in Kaunas city.

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
Several studies reported statistically significant associations of blood pressure (BP) with short-term air temperature variability (TV), but the effect of TV on BP was found to differ in different areas. This study aimed to detect the association between BP and TV in Kaunas, Lithuania. Data from the international Health, Alcohol, and Psychosocial Factors in Eastern Europe study was used to gather information on the participants' BP during 2006-2008. The TV variables were the diurnal temperature range (DTR), the standard deviation (SD) of hourly temperature during the 24 h (TSD) and the first 12 h of the day (TSDF), and the SD of daily minimum and maximum temperatures during the exposure days (DTV). Multiple linear regression was used after controlling for potential confounders. Among the participants, 45.5% were men, 30.9% were aged > 65 years, and 9.8% were normotensive. A positive association of systolic BP with TSD on the same day (TSD0), DTR with lags of 0-2 days, and DTV with lags of 0-1 day and of diastolic BP with TSD0 and TSDF was found, a stronger impact being observed in males and in physically active participants. The impact of TV was stronger at lower temperatures, and a statistically significant negative interaction between air temperature and TV variables was found. In May-June, a negative association of DTV with diastolic BP was observed. We found a positive association of BP with TV. Sex, the level of physical activity, and air temperature may modify the relationship between TV and BP.
