Circulating thrombospondin 1 level as a surrogate marker in patients receiving cyclophosphamide-based metronomic chemotherapy.
Trial report in Investigational new drugs, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Several previous reports suggest that thrombospondin (TSP-1) may be a mediator of the antiangiogenic effects of low-dose metronomic cyclophosphamide-based chemotherapy (MC). We conducted a randomized phase II trial evaluating megestrol acetate (n = 44) versus MC (n = 44) in patients having exhausted all standard treatments. We measured the TSP-1 levels at baseline and D15. We did not observe significant differences in TSP-1 at baseline in the two arms (p = 0.07). TSP-1 levels decreased in patients receiving metronomic cyclophosphamide (from 16.6 ± 7.2 µg/ml to 12.8 ± 7.4 µg/ml; p = 0.057). The TSP-1 level was stable in patients receiving megestrol acetate. Nevertheless, the TSP-1 level driven by MC did not correlate to clinical benefit.
