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.
Ratios
No significant association between incident hypertension and GLP-1RAs was detected, except for the association between exenatide-10 μg-twice-daily and sulfonylureas (OR, 0.40, 95% CI: 0.16, 0.82).

Differences
Compared with placebo, insulin, and sulfonylureas, GLP-1RAs decreased systolic blood pressure with range from -1.84 mmHg (95% CI: -3.48 to -0.20) to -4.60 mmHg (95% CI: -7.18 to -2.03).
Compared with placebo, insulin, and sulfonylureas, GLP-1RAs decreased systolic blood pressure with range from -1.84 mmHg (95% CI: -3.48 to -0.20) to -4.60 mmHg (95% CI: -7.18 to -2.03).
Compared with placebo, a reduction in diastolic blood pressure was detected significantly only for exenatide-10 μg-twice-daily (-1.08 mmHg, 95% CI: -1.78 to -0.33).

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
The marked sentences are the ones the graph read a number from.
aimsTo evaluate current evidence of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on blood pressure, heart rate, and hypertension in patients with type 2 diabetes.
methodsMedline, Embase, the Cochrane library, and the website www.clinicaltrials.gov were searched on April 5th, 2014. Randomized-controlled trials with available data were included if they compared GLP-1RAs with placebo and traditional antidiabetic drugs in patients with type 2 diabetes with duration ≥ 12 weeks. Weighted mean difference for blood pressure and heart rate, odds ratio (OR) for hypertension were calculated by random-effect model. Network meta-analysis was performed to supplement direct comparisons.
resultsSixty trials with 14 treatments were included. Compared with placebo, insulin, and sulfonylureas, GLP-1RAs decreased systolic blood pressure with range from -1.84 mmHg (95% CI: -3.48 to -0.20) to -4.60 mmHg (95% CI: -7.18 to -2.03). Compared with placebo, a reduction in diastolic blood pressure was detected significantly only for exenatide-10 μg-twice-daily (-1.08 mmHg, 95% CI: -1.78 to -0.33). Exenatide (2 mg once weekly), liraglutide 1.2 mg once daily), and liraglutide (1.8 mg once daily) increased heart rate by 3.35 (95% CI: 1.23-5.50), 2.06 (95% CI: 0.43, 3.74), and 2.35 (95% CI: 0.94-3.76) beats/min versus placebo. This effect was evident compared with active control (range: 2.22-3.62). No significant association between incident hypertension and GLP-1RAs was detected, except for the association between exenatide-10 μg-twice-daily and sulfonylureas (OR, 0.40, 95% CI: 0.16, 0.82).
conclusionsGLP-1RAs were associated with modest reduction on blood pressure, a slight increase in heart rate, yet no significant association with hypertension. Further investigation to explore mechanisms is warranted.
