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

Osteosarcoma patients are commonly treated with high doses of methotrexate (MTX). MTX is an analog of folate, which is essential for DNA synthesis. Genetic polymorphism at single nucleotide can be indicative to the prognostic outcome in patients. Germ-line variants in candidate genes, coding for enzymes active in the metabolism of MTX, were studied in 62 osteosarcoma patients. Patients harboring the GG genotype in reduced folate carrier 1 (RFC1) rs1051266 had significantly better survival in comparison with patients having the AA genotype (P=0.046). These patients also had a lower frequency of metastasis (15%, P=0.029). Also patients homozygous for the G allele of rs1053129 in the dihydrofolate reductase (DHFR) gene were more likely to have a metastasis (45%, P= 0.005), and the methylenetetetrahydrofolate reductase (MTHFR) 677C allele was associated with higher degree of liver toxicity (88%, P=0.007). The study suggests that germ-line variants in the MTX metabolic pathway are associated with survival and side effects in patients treated with MTX.
