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

backgroundThe objective of this meta-analysis was to evaluate the efficacy of the metabolic agent trimetazidine (TMZ) as monotherapy in the treatment of stable angina pectoris, from echocardiography and radionuclide angiography data. HYPOTHESIS: Treatment with TMZ proved to be as effective as other first-line antianginal agents for coronary patients, and it provided additional efficacy in combination with hemodynamic agents.

methodsA search of the literature published between 1965 and 2008 was performed on the MEDLINE and EMBASE databases. Only randomized, controlled trials were included in this meta-analysis. Patients had to be treated for at least 2 weeks with data on the following 4 parameters at baseline and at the end of the treatment period: left ventricular ejection fraction (LVEF), LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), and wall motion score index (WMSI). The quality of the trials was assessed by the Jadad score.

resultsEleven clinical studies meeting our criteria were analyzed. Results showed that TMZ significantly improved LVEF, with a mean increase of 6.88% (95% confidence interval [CI]: 5.50-8.25), and significantly reduced LVESV by 11.58 mL (95% CI: 5.79-17.37) and WMSI by 0.23 (95% CI: 0.07-0.38). Changes in LVEDV were variable. In both the long term and the short term, TMZ can improve LV function. The efficacy was unchanged in patients with diabetes mellitus.

conclusionsThis meta-analysis confirmed the efficacy of TMZ monotherapy in improving LV function compared with placebo.
