1 · What the graph read from 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.

2 · The registry

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

objectiveEvaluate 25-year trends in coronary revascularization volumes and outcomes in British Columbia (BC).

methodsAll revascularizations in BC, Canada, between 2000-2024 were identified using provincial administrative datasets within the single-payer public health system serving 5.5 million persons. Cases were defined as any combination of PCI and/or CABG occurring within 60 days, categorized as One-Time PCI, Serial PCI, CABG, or Combination CABG + PCI. Temporal trends were assessed using linear regression and changepoint analysis. Statistical significance was set at α = 0.05.

resultsWe identified 239,461 revascularization cases involving 563,994 vessel revascularizations. Annual case volumes per capita rose until 2005, remained stable until 2017, and then declined sharply (-9.06/100,000/year, p < 0.001). PCI and CABG accounted for 73.6% and 24.9% of cases, respectively. CABG use declined until the mid-2000s and stabilized thereafter at 25% of cases (15% for acute MI). Mean number of vessels treated per case increased modestly over time (+ 0.01 vessels/case/year, p = 0.003). Mean age at revascularization increased + 0.17 years/year (p < 0.001) from 67.2 to 71.1. Thirty-day mortality was 2.21%; 30-day CABG mortality declined annually (-0.04%/year, p < 0.001) from 2.14% to 1.46%, but PCI mortality increased (+ 0.05%/year, p < 0.001) from 1.60% to 2.46%.

conclusionsPCI has predominated since 2001, whereas CABG utilization stabilized after 2005. BC has experienced an ongoing revascularization recession since 2017.
