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

purposeClinical trials have reported conflicting results as to whether taxane-based doublet improves outcome over single-agent taxane in patients with advanced breast cancer.

methodsWe performed a meta-analysis comparing primary and secondary end points of taxane-based doublet with single-agent taxane chemotherapy in patients with advanced breast cancer and prior anthracycline treatment. The event-based relative risk ratio (RR) with 95% confidence intervals (95% CI) was derived, and a test of heterogeneity was applied.

resultsFour eligible trials (2,343 patients) were selected from 488 studies that initially were identified. A significant difference in favoring taxane-based doublet over single-agent taxane was observed in progression-free survival (PFS) (RR, 1.33; 95% CI, 1.02-1.75; P = 0.039) and partial response (PR) (RR, 1.43; 95% CI, 1.10-1.86; P = 0.008). The ORR was higher for patients receiving taxane-based doublet, although not statistically significant (RR, 1.17; 95% CI, 0.91-1.50; P = 0.220). Whereas there was no difference in 1-year survival rate (1-year SR) (RR, 1.05; 95% CI, 0.94-1.17; P = 0.422), clinical benefit (CB) (RR, 1.02; 95% CI, 0.95-1.09; P = 0.642), and complete response (CR) (RR, 0.75; 95% CI, 0.31-1.79; P = 0.512). Toxicities did not differ significantly except stomatitis and diarrhea.

conclusionTaxane-based doublet appeared to improve PFS and PR compared with single-agent taxane in the treatment of patients with advanced breast cancer. Further prospective, randomized, controlled trials will be necessary.
