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

Xeroderma pigmentosum group D (XPD) participates in DNA unwinding during nucleotide excision repair, which may alter the efficacy of platinum-based chemotherapy. We analyzed the influence of codon 751 Lys-->Gln polymorphism of XPD on its protein expression levels, clinico-pathological features, and outcome of 188 Chinese patients with metastatic colorectal carcinoma (CRC) that had been treated with first-line Oxaliplatin + Leucovorin + 5-Fluorouracil (FOLFOX-4) chemotherapy. The results showed that in comparison with Caucasian populations, a remarkably lower prevalence of Lys/Gln genotype was noted (16%, n = 30). No between-group difference in XPD protein expression of patients with or without this polymorphism was noted (56.5%vs 59.7%; P = 0.783). Patients with Gln751 allele have a significantly lower response to FOLFOX-4 treatment (36.7%vs 58.2%, P = 0.03), and shorter progression-free (7 vs 11 months; P < 0.01) and overall (14 vs 22 months; P < 0.01) survivals. The incidence of grade 3/4 oxaliplatin-neuropathies was very similar in both groups (13.3%vs 16.5%; P = 0.67). By adjusted analysis, this polymorphism was further identified as an independent prognostic factor (P = 0.03). These data suggest that Asian populations have a significantly lower prevalence of codon 751 Lys/Gln polymorphism in XPD, which could be a key determinant for good response to oxaliplatin-based treatment and favorable outcomes.
