Effects of guar gum ingestion on postprandial blood pressure in older adults.
Trial report in The journal of nutrition, health & aging, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesThe aim of this study was to investigate the effects of guar gum on postprandial blood pressure in older people.
designA randomized, double-blind, placebo-controlled, cross-over design.
settingCommunity senior centers in B city, South Korea.
participantsTwenty-two older female adults aged 67 to 88 with postprandial hypotension.
interventionThe participants were randomly assigned to guar gum (semi-fluid food with 9 gram) or placebo intervention during the first treatment phase. After a washout period of 1 week, the two interventions were switched to the other in the second treatment phase. MEASUREMENTS: Blood pressure was measured during both phases before having a meal and every 15 minutes during 120 minutes after a meal with automated sphygmomanometer.
resultsChange in systolic blood pressure (SBP) over time was significantly different between guar gum and placebo groups (F=4.07, p=0.001). Compared with placebo group, guar gum group had significantly low prevalence of postprandial hypotension (PPH) (guar gum group=18.2% vs. placebo group=72.7%; χ² =13.20, p<0.001). It also had significant difference in change of diastolic blood pressure (DBP) over time between guar gum and placebo groups (F=2.49, p=0.027).
conclusionThis findings show that guar gum could be effective on postprandial drops in blood pressure in older female adults.
