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

backgroundPemetrexed is common cytotoxic chemotherapy among non-squamous non-small cell lung cancer (non-Sq-NSCLC) patients; however, among epidermal growth factor receptor (EGFR)-positive lung cancer, there is no clear evidence to support the efficacy of sequential treatment with pemetrexed. MATERIAL AND

methodsWe performed a post-hoc analysis of subsequent chemotherapies among 144 patients who received the post-protocol treatment in the phase III trial WJTOG 3405 comparing gefitinib to cisplatin plus docetaxel, and analyzed the effect of pemetrexed on overall survival (OS).

resultsPatients with treatment including pemetrexed exhibited significantly longer OS in comparison to those without pemetrexed; the median OS in the pemetrexed + and pemetrexed- patients were 40.7 months and 28.0 months, respectively (0.55 of HR [95% CI: 0.38-0.80, p = 0.0020]). On the other hand, other treatments, including docetaxel, TS-1 and paclitaxel showed no significant impact on OS. The multivariate analysis with a time-dependent Cox proportional hazards model showed that treatment including pemetrexed, as well as PS 0 and post-operative recurrence, were independent predictors of a good prognosis. Moreover, among patients who received at least four lines of prior treatment, pemetrexed + treatment also significantly prolonged OS in comparison to pemetrexed- treatment (median OS pemetrexed + vs. pemetrexed-: 44.4 months vs. 32.6 months; HR: 0.55 [95% CI: 0.31-0.94, p = 0.0290]).

conclusionsSequential treatment including pemetrexed against EGFR-mutated NSCLC might be associated with a better outcome. It was considered that pemetrexed should be administered without fail as a sequential treatment to improve the prognosis of EGFR-mutated NSCLC as well as like EGFR-tyrosine kinase inhibitors.
