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
purposeResearch regarding Custodiol's safety in minimally invasive mitral valve repair remains limited in Asian populations. We compared Custodiol in minimally invasive mitral valve repair to repetitive cold blood cardioplegia in open mitral valve repair.
methodsWe retrospectively evaluated 98 consecutive patients who underwent minimally invasive mitral valve repair with Custodiol and 70 consecutive patients who underwent open mitral valve repair with repetitive cold blood cardioplegia at our institution between January 2015 and December 2024. The primary endpoints were creatine kinase-myocardial band (MB) levels and left ventricular ejection fraction determined by echocardiography pre- and post-surgery.
resultsMaximum creatine kinase-MB levels within 48 h post-surgery were significantly lower in the minimally invasive group than in the open repair group, both in the overall cohort (45.0 vs. 60.7 U/L; p <0.001, respectively) and after excluding patients who underwent Maze procedure or pulmonary vein isolation (42.4 vs. 50.0 U/L; p = 0.009, respectively). Left ventricular ejection fraction pre- and post-surgery was comparable between the minimally invasive and open repair groups (72% vs. 69%; p = 0.426 and 59% vs. 60%; p = 0.204, respectively).
conclusionCustodiol during minimally invasive mitral valve repair provides myocardial protection comparable to repetitive cold blood cardioplegia in open mitral valve repair.
