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

backgroundDiabetes mellitus is one of the risk factors for coronary artery disease and frequently associated with multivessels disease and poor clinical outcomes. Long term outcome of successful revascularization of chronic total occlusions (CTO) in diabetes patients remains controversial. METHODS AND

resultsFrom January 2005 to December 2015, 739 patients who underwent revascularization for CTO in Taipei Veterans General Hospital were included in this study, of which 313 (42%) patients were diabetes patients. Overall successful rate of revascularization was 619 (84%) patients whereas that in diabetics and non-diabetics were 265 (84%) and 354 (83%) respectively. Median follow up was 1095 days (median: 5 years, interquartile range: 1-10 years). During 3 years follow-up period, 59 (10%) in successful group and 18 (15%) patients in failure group died. Although successful revascularization of CTO was non-significantly associated with better outcome in total cohort (hazard ratio (HR): 0.593, 95% confidence interval (CI) 0.349-0.008, P: 0.054), it might be associated with lower risk of all-cause mortality (HR: 0.307, 95% CI 0.156-0.604, P: 0.001) and CV mortality (HR: 0.266, 95% CI 0.095-0.748, P: 0.012) in diabetics (P: 0.512). In contrast, successful CTO revascularization didn't improve outcomes in non-diabetics (all P > 0.05). In multivariate cox regression analysis, successful CTO revascularization remained an independent predictor for 3-years survival in diabetic subgroup (HR: 0.289, 95% CI 0.125-0.667, P: 0.004). The multivariate analysis result was similar after propensity score matching (all-cause mortality, HR: 0.348, 95% CI 0.142-0.851, P: 0.021).

conclusionsSuccessful CTO revascularization in diabetes may be related to better long term survival benefit but not in non-diabetic population.
