Outcomes of percutaneous coronary intervention for chronic total occlusions in the elderly: A systematic review and meta-analysis.
Synthesis in Clinical cardiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 3 of them syntheses 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
objectiveThis study aimed to compare outcomes of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) in the elderly (≥75 years) versus nonelderly and assess the impact of successful CTO-PCI in the elderly.
methodsPubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases were searched up to October 1, 2020. Mortality rates and major adverse cardiac events (MACE) were compared between elderly and nonelderly patients and successful versus failed CTO-PCI in the elderly.
resultsEight studies were included. Meta-analysis indicated no statistically significant difference in the risk of in-hospital mortality (RR: 1.97 95% CI: 0.78, 4.96 I
conclusionsElderly patients may have a tendency of higher in-hospital MACE with significantly increased long-term mortality and MACE after CTO-PCI. The success of PCI is significantly lower in the elderly. In elderly patients with successful PCI, the risk of long-term mortality and MACE is significantly reduced.
