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

introductionThe female gender has been shown as high-risk factor for mortality and morbidity. We sought to assess the influence of female gender on coronary artery bypass graft (CABG) surgery from our own experience.

methodsThis is a retrospective analysis of prospectively collected database from a single centre. Patients were grouped according to gender and potential differences in pre-operative, intra-operative and post-operative factors were explored. Significant high-risk factors were then fitted in a multivariate model to account for differences in predicting gender influence on surgical outcomes.

resultsTwo thousand eight hundred and four consecutive patients underwent isolated first-time CABG between February 2000 and December 2008; 562 (20%) patients were females. Pre-operatively, females were more likely to have significant comorbidities (age, congestive cardiac failure, hypercholesterolemia, hypertension, ischemic heart disease, peripheral vascular disease, pre-op arrhythmias, small body surface area and poor ejection fraction (p < 0.001)) consistent with higher Euroscore (p > 0.0001) and more urgent surgery (p < 0.002). Intra-operatively, they showed less extent pattern of disease requiring less bypass and cross-clamp time (p < 0.001). Observed surgical mortality was significantly higher in females (3.6 vs. 2.1%, p < 0.042); however, after adjusting for propensity score and significant factors identified in multivariate models, females only independently predicted a higher wound infection, lower neurological complications, lower rate of re-sternotomy, longer hospital stay and post-surgery stay (p < 0.01).

conclusionsDespite higher risk profile and higher observed surgical mortality, early outcomes in females were similar to their matched males' counterpart in isolated CABG surgery. Females were associated with higher incidence of wound infections but lower rate of neurological complications.
