Effectiveness and Tolerability of Ivabradine with or Without Concomitant Beta-Blocker Therapy in Patients with Chronic Stable Angina in Routine Clinical Practice.
Article in Advances in therapy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
introductionIn the prospective, open-label, non-interventional, multicenter RESPONSIfVE study, the effectiveness, response rates and tolerability of ivabradine with or without beta blocker (BB) were evaluated in patients with chronic stable angina pectoris (AP) in daily clinical practice.
methodsIn patients with AP, ivabradine was given twice daily in flexible doses for 4 months. Resting heart rate (HR), number of angina attacks, short-acting nitrate use, severity of symptoms [by Canadian Cardiovascular Society (CCS) score] and tolerability with or without existing BB therapy were documented and analyzed using descriptive statistical methods.
resultsIn total, 1250 patients with AP (mean age 66.0 ± 10.9 years, 59.6% male, 31.9% previous myocardial infarction) and an indication for ivabradine were included. Sixty-five percent of all patients received BB. Further concomitant standard medication included aspirin (74.2%), statins (69.3%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (84.2%), diuretics (40.0%), long-acting nitrates (15.7%), and calcium antagonists (21.4%). After 4 months of ivabradine treatment (mean daily dose 11.0 ± 2.7 mg), mean HR was reduced from 82.4 ± 11.8 beats per minute (bpm) to 67.1 ± 8.4 bpm. The average number of angina attacks/week decreased from 1.2 ± 1.9 to 0.1 ± 0.6 and the average use of short-acting nitrates/week from 1.5 ± 2.8 units to 0.2 ± 1.0 units. CCS classification of patients improved from 76% classified in CCS grades II or III and 24% in CCS grade I to 66% classified in CCS grade I and only 35% remaining in CCS grades II or III at study end. Response rate to ivabradine (defined as HR <70 bpm or HR reduction ≥10 bpm) reached 87%. HR reduction, symptomatic improvement and response rates were comparable in patients with or without BB. Adverse drug reactions were reported for 2.2% of patients.
conclusionIn this prospective study over a four-month period in clinical practice, ivabradine effectively reduced HR, angina attacks, and nitrate consumption in patients with AP with or without concomitant BB therapy. Ivabradine improved CCS scores and achieved a high treatment response rate with good general tolerability.
