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

Introduction: Anaplastic lymphoma kinase (ALK) inhibitors (ALKi) are the standard treatment for metastatic, ALK-positive non-small cell lung cancer (NSCLC). Second- and third-generation ALKi, including alectinib, brigatinib, ensartinib, envonalkib, and lorlatinib, have shown better efficacy than crizotinib. However, due to the lack of direct head-to-head comparisons among these agents, the optimal treatment for metastatic ALK-positive NSCLC remains unclear. Methods: This study used the IPDfromKM (Individual Patient Data from Kaplan-Meier) method to reconstruct patient-level data from Kaplan-Meier curves of seven randomized phase III trials, involving a total of 3,850 patients. Crizotinib arms were pooled as the common comparator. Progression-free survival (PFS) was the primary endpoint, assessed using Cox proportional hazards models and restricted mean survival time (RMST). Subgroup analyses focused on patients with baseline central nervous system (CNS) metastases. Results: All ALKi significantly improved PFS compared to crizotinib. Lorlatinib showed the most meaningful improvement, with the greatest benefit in both overall PFS (HR=0.28; 95% CI 0.21-0.38) and CNS PFS (HR=0.09; 95% CI 0.04-0.2). In direct comparisons, lorlatinib outperformed brigatinib (HR=0.59; 95% CI 0.39-0.87) and envonalkib (HR=0.52; 95% CI 0.35-0.77) in terms of PFS. While lorlatinib also showed improved PFS compared to alectinib (HR=0.72; 95% CI 0.50-1.04) and ensartinib (HR=0.73; 95% CI 0.48-1.10), these differences were not statistically significant. Lorlatinib demonstrated the greatest benefit in PFS among patients with baseline CNS metastases. Conclusion: In this indirect comparison using reconstructed patient data, lorlatinib emerged as the most effective ALKi, showed the most favorable HR for PFS compared to the other ALKi, although it did not reach statistical significance versus alectinib and ensartinib. Additionally, lorlatinib showed the highest efficacy in the control of CNS progression.
