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.
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
introductionTo investigate the value of baseline serum levels of VEGF, bFGF, endostatin and their ratio as predictive factors of response to endocrine therapy in patients with metastatic breast cancer (MBC) and positive ER treated with letrozole after tamoxifen failure. MATERIALS AND
methodThe serum levels of endostatin, VEGF and bFGF were determined in postmenopausal patients with progressing MBC from serum samples obtained before initiation of letrozole. The relation between serum angiogenic factor levels and TTP was investigated.
resultsSeventy-six patients (45.2%) presented a high endostatin level (> 24.6 ng/ml), 40% low bFGF levels (0 pg/ml) and 50.4% low VEGF (=/< 187 ng/ml). With a median follow-up of 22 months, the median TTP was 12.3 months. Median TTP was worse in patients with high endostatin concentration as well as in the low bFGF group, but was not affected when VEGF was considered. When the two factors were combined, the median TTP of patients with endostatin > 24.6 ng/ml and bFGF equal 0 pg/ml was 9.5 months versus 19.5 months in patients with endostatin =/< 24.6 ng/ml and bFGF > 0 pg/ml.
conclusionsThe baseline levels of bFGF and endostatin are predictive factors of efficacy in patients with MBC treated with letrozole and can select groups with different TTP.
