Randomized Phase 2 Trial of Pharmacodynamic Separation of Pemetrexed and Intercalated Erlotinib Versus Pemetrexed Alone for Advanced Nonsquamous, Non-small-cell Lung Cancer.
Trial report in Clinical lung cancer, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
backgroundPharmacodynamic separation of pemetrexed and erlotinib avoids negative cellular interactions and results in antitumor synergy in erlotinib-resistant non-small-cell lung cancer (NSCLC) cells, independent of EGFR (epidermal growth factor receptor) genotype. PATIENTS AND
methodsPatients with platinum-treated metastatic nonsquamous NSCLC were randomly assigned 1:2 to pemetrexed alone (500 mg/m
resultsOf 83 patients enrolled, 79 were randomized to either pemetrexed alone (n = 27) or in combination (n = 52). Fifty-nine (79%) of 75 eligible patients had tumors with confirmed EGFR genotype: 7 with activating mutations and 52 wild type. Median PFS was 4.7 and 2.9 months in the combination and pemetrexed-alone groups, respectively. In patients with EGFR wild-type tumors, median PFS was 5.3 and 3.5 months in the combination and pemetrexed-alone groups, respectively. Objective response rate (29% vs. 10%, P = .17), 6-month PFS (45% vs. 29%, P = .26), and 12-month PFS (23% vs. 10%, P = .28) were all higher in the combination arm. Rash (67% vs. 26%, P = .0007) and diarrhea (44% vs. 11%, P = .003) were significantly more common in the combination arm.
conclusionIn patients with unselected or EGFR wild-type advanced nonsquamous NSCLC, pharmacodynamic separation of pemetrexed and intercalated erlotinib had promising antitumor activity without new safety concerns. The combination merits further evaluation as maintenance or second-line therapy against new standards in patients with EGFR wild-type advanced NSCLC.
