Hypertrophic obstructive cardiomyopathy-the Leipzig experience.
Article in Annals of cardiothoracic surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundManagement of hypertrophic obstructive cardiomyopathy (HOCM) has evolved considerably over the last fifty years, and includes medical treatment as well as septal myectomy (SM) to relief symptoms caused by left ventricular outflow tract obstruction (LVOTO). We report the Leipzig Heart Center experience in the surgical management of patients with HOCM.
methodsWe collected data from all patient treated surgically with a myectomy for LVOTO in patients with HOCM between 1997 and 2016. Patients with absent data were excluded from our analysis. All data were obtained from our surgical database and analyzed retrospectively.
resultsWe identified 115 patients who underwent surgical treatment for HOCM, where a male:female ratio of 1.1:1, a mean age of 60.8±14.6 years and a body mass index of 27.7±4.5 were observed. The most common symptom was dyspnea (n=102). Of all patients, 50% had New York Heart Association (NYHA) III class symptoms. Arterial hypertension was the most common comorbidity (n=80). Preoperative transthoracic echocardiography showed a mean ejection fraction (EF) of 65.9%±9.7%, median septal thickness of 21.1±5.3 mm, systolic anterior motion of the mitral valve (MV) in 61.7% of patients, and mean LVOT gradient of 70.1±45.2 mmHg. Surgery resulted in a mean decrease of the septal thickness by 15±3.7 mm and LVOT gradient by 9.7±8.5 mmHg. Isolated SM was carried out on 20 patients. Postoperatively, we were able to notice a significant improvement in NYHA classification, in which patients with NYHA III benefitted most from SM. Long-term follow-up data up to 11.3±0.7 years were available for 114 patients. During follow-up, 16 patients died, and one patient was lost to follow up.
conclusionsSurgical treatment of LVOT in patients with HOCM is an effective intervention that improves cardiac function and quality of life (QoL) and is associated with a low operative risk.
