1 · What the graph read from 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.

Abstract

Recent studies have suggested a link between exposure to ambient particulate matter <2.5 microm in diameter (PM(2.5)) and adverse cardiovascular outcomes. The objective of this study was to examine the effects of differing community-level exposure to PM(2.5) on daily measures of blood pressure (BP) among an adult population. During the period May 2002 through April 2003, BP was examined at 2 time points for 347 adults residing in 3 distinct communities of Detroit, Michigan. Exposure to PM(2.5) was assessed in each community during this period, along with multivariate associations between PM(2.5) and BP. In models combining all 3 of the communities, PM(2.5) was significantly associated with systolic blood pressure; a 10-microg/m(3) increase in daily PM(2.5) was associated with a 3.2-mm Hg increase in systolic blood pressure (P=0.05). However, in models that added a location interaction, larger effects were observed for systolic blood pressure within the community with highest PM(2.5) levels; a 10-microg/m(3) increase in daily PM(2.5) was associated with a 8.6-mm Hg increase in systolic blood pressure (P=0.01). We also found young age (<55 years) and not taking BP medications to be significant predictors of increased BP effects. Among those taking BP medications, the PM(2.5) effect on BP appeared to be mitigated, partially explaining the age effect, because those participants <55 years of age were less likely to take BP medications. Short-term increases in exposure to ambient PM(2.5) are associated with acute increases in BP in adults, especially within communities with elevated levels of exposure.
