Sequential therapy with crizotinib and a second-generation ALK inhibitor versus direct therapy of a second-generation ALK inhibitor in
Article in Journal of thoracic disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: There are few real-world studies in which the efficacy of sequential crizotinib and second-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) are compared with direct therapy of second-generation ALK TKI in Methods: Between May 2014 and October 2022, 211 patients from the Zhejiang Cancer Hospital who harbored Results: Of the 211 lung cancer patients with Conclusions: There was no statistical difference in efficacy between first-generation sequential second-generation ALK TKIs and direct therapy of second-generation ALK TKI regimens. The CNS efficacy of the direct second-generation group was better than that of the sequential therapy group. The prognostic factors for PFS included PS and brain metastases, while the prognostic factors for OS, PS and liver metastases were included.
