Dose intensification of methotrexate and cytarabine during intensified continuation chemotherapy for high-risk B-precursor acute lymphoblastic leukemia: POG 9406: a report from the Children's Oncology Group.
Trial report in Journal of pediatric hematology/oncology, 2014. 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
purposeTo determine the efficacy and toxicity of higher dose versus standard dose intravenous methotrexate (MTX) and pulses of high-dose cytosine arabinoside with asparaginase versus standard dose cytosine arabinoside and teniposide during intensified continuation therapy for higher risk pediatric B-precursor acute lymphoblastic leukemia (ALL). PATIENTS AND
methodsFrom 1994 to 1999, the Pediatric Oncology Group conducted a randomized phase III clinical trial in higher risk pediatric B-precursor ALL. A total of 784 patients were randomized in a 2×2 factorial design to receive MTX 1 g/m versus 2.5 g/m and to cytosine arabinoside/teniposide versus high-dose cytosine arabinoside/asparaginase during intensified continuation therapy.
resultsPatients receiving standard dose MTX had a 5-year disease-free survival (DFS) of 71.8±2.4%; patients receiving higher dose MTX had a 5-year DFS of 71.7±2.4% (P=0.55). Outcomes on cytosine arabinoside/teniposide (DFS of 70.4±2.4) were similar to higher dose cytosine arabinoside/asparaginase (DFS of 73.1±2.3%) (P=0.41). Overall survival rates were not different between MTX doses or cytosine arabinoside/teniposide versus cytosine arabinoside/asparaginase.
conclusionsIncreasing MTX dosing to 2.5 g/m did not improve outcomes in higher risk pediatric B-precursor ALL. Giving high-dose cytarabine and asparaginase pulses instead of standard dose cytarabine and teniposide produced nonsignificant differences in outcomes, allowing for teniposide to be removed from ALL therapy.
