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

backgroundPrevious data suggest significant ethnic differences in outcomes following percutaneous coronary revascularization (PCI), though previous studies have focused on subgroups of PCI patients or used administrative data only. We sought to compare outcomes in a population-based cohort of men and women of South Asian (SA), Chinese and "Other" ethnicity.

methodsUsing a population-based registry, we identified 41,792 patients who underwent first revascularization via PCI in British Columbia, Canada, between 2001 and 2010. We defined three ethnic groups (SA, 3904 [9.3%]; Chinese, 1345 [3.2%]; and all "Others" 36,543 [87.4%]). Differences in mortality, repeat revascularization (RRV) and target vessel revascularization (TVR), at 30 days and from 31 days to 2 years were examined.

resultsAdjusted mortality from 31 days to 2 years was lower in Chinese patients than in "Others" (hazard ratio [HR] 0.72; 95% confidence interval [CI] 0.53-0.97), but not different between SAs and "Others". SA patients had higher RRV at 30 days (adjusted odds ratio [OR] 1.30; 95% CI: 1.12-1.51) and from 31 days to 2 years (adjusted hazard ratio [HR] 1.17; 95% CI: 1.06-1.30) compared to "Others". In contrast, Chinese patients had a lower rate of RRV from 31 days to 2 years (adjusted HR 0.79; 95% CI: 0.64-0.96) versus "Others". SA patients also had higher rates of TVR at 30 days (adjusted OR 1.35; 95% CI: 1.10-1.66) and from 31 days to 2 years (adjusted HR 1.19; 95% CI: 1.06-1.34) compared to "Others". Chinese patients had a lower rate of TVR from 31 days to 2 years (adjusted HR 0.76; 95% CI: 0.60-0.96).

conclusionsSA had higher RRV and TVR rates while Chinese Canadians had lower rates of long-term RRV, compared to those of "Other" ethnicity. Further research to elucidate the reasons for these differences could inform targeted strategies to improve outcomes.
