Trial reportJournal of clinical hypertension (Greenwich, Conn.)2011
Accuracy of blood pressure measurements reported in an electronic medical record during routine primary care visits.
Trial report in Journal of clinical hypertension (Greenwich, Conn.), 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
Electronic medical records (EMRs) allow for real-time access to blood pressure (BP) information on a population basis and improve identification and treatment of individuals with hypertension. Despite the potential uses of the data available from EMRs, relatively little research has examined the reliability of this data. To address this gap, the authors examined the reliability of BP taken at primary care visits and recorded in an EMR with those taken at a research study visit at which standard protocols were used to measure BP among all adults as well as by sex and age. Systolic BP (SBP) averaged 3.7 (17.3) points and diastolic BP (DBP) was 2.8 (10.6) points lower in the EMR than in the study visit across age and sex groups, with all differences statistically significant. For this cohort of patients with a diagnosis of hypertension, there was moderate correlation between BP measurements taken in clinic and at research. However, BP control for individuals, as defined by an SBP <140 mm Hg and DBP 90 mm Hg, differed by almost 25%. Known variability of BP and clinic procedures for measuring and recording BP may account for these differences.
