Cardiac Resynchronization Therapy Leads to Improvements in Handgrip Strength.
Article in Cardiology research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundA reduction in skeletal muscle performance measured by handgrip strength is common in heart failure. No trial has investigated the role of cardiac resynchronization therapy, which leads to improvements in cardiac performance, on the function of skeletal muscle in patients with heart failure.
methodsNineteen patients were recruited, 18 male, age 69 ± 8 years, New York Heart Association class II-IV, QRS duration 173 ± 21 ms and left ventricular ejection fraction 26±8%. Handgrip strength was measured at baseline before, and 6 and 12 months, following cardiac resynchronization therapy. Response was assessed using quality of life questionnaire, 6-minute walk distance, left ventricular end-diastolic volume, and cardiopulmonary exercise testing at the same time points.
resultsFourteen patients were identified as responders, demonstrating significant improvements in all four markers of response. There was no significant difference at baseline in left or right handgrip strength between responders and non-responders. Compared to baseline, handgrip strength significantly increased in responders during follow-up, left (34.4 ± 11.4 to 40.3 ± 11.3 kgf, P < 0.001) and right (35.7 ± 12.5 to 42.2 ± 11.5 kgf, P < 0.001) at 12 months. No such improvement was seen in non-responders.
conclusionsThis study demonstrates that positive response to cardiac resynchronization therapy is associated with significant gains in handgrip strength, suggesting that cardiac resynchronization therapy may indirectly lead to secondary gains in skeletal muscle function.
