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

aimsGemcitabine has been associated with an increased risk of arterial and venous thromboembolic events (ATEs and VTEs), although the overall risk remains unclear. As indications for its use in oncology are expanding, a comprehensive characterization of these complications becomes imperative.

methodsPubmed was searched for articles published from 1 January 1990 to 31 December 2012. Eligible studies included prospective randomized controlled phase II and III trials evaluating gemcitabine based vs. non-gemcitabine based chemotherapy in patients with solid tumours. Data on VTEs and ATEs were extracted. Overall incidence rates, odds ratio (OR), and 95% confidence intervals (CIs) were calculated employing fixed or random effects models depending on the heterogeneity of included trials.

resultsA total of 4845 patients from 19 trials were included. Among patients treated with gemcitabine based chemotherapy, the overall incidence of VTEs (13 studies comprising 3823 patients) and ATEs (eight studies consisting of 2431 patients) was 2.1% (95% CI 1.2%, 3.8%) and 2.2% (95% CI 1.4%, 3.2%). The associated ORs of VTEs and ATEs were 1.56 (95% CI 0.86, 2.83, P = 0.15) and 1.82 (95% CI 0.89, 3.75, P = 0.10) compared with non-gemcitabine based therapy. A tendency to increase the risk of ATE and VTEs was also detected in any prespecified subgroup.

conclusionThe use of gemcitabine does not significantly increase the risk of VTEs and ATEs in patients with solid tumours when compared with non-gemcitabine based chemotherapy.
