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: The standard of care for non-small cell lung cancer (NSCLC) patients who encounter progression on initial immune checkpoint inhibitor (ICI) based treatment is uncertain. In the real world, there are various subsequent treatment options, but how to find the most suitable treatment for different patients is still unknown. The present study aimed to explore prognostic factors of subsequent treatment after progression (STAP) (defined as the next treatment after progression from the initial immunotherapy) of initial immunotherapy. Methods: In this retrospective cohort study, NSCLC patients received regimens after progression of initial immunotherapy at Beijing Chest Hospital, Capital Medical University, between March 2016 and May 2023 were retrieved. The major efficacy endpoint was progression-free survival 2 (PFS2), defined as the time from the initiation of next treatment after initial immunotherapy failure to disease progression or death from any cause. Subgroup analyses were conducted according to baseline characteristics, some subsequent regimens beyond progression, etc. for prognostic factors exploration. The Cox proportional hazards model was used for multivariate analysis. Results: There were 176 patients enrolled. Median age was 64 years. There were 36 (20.5%) females, and 123 (69.9%) were smokers. Adenocarcinoma (99, 56.2%) was the major histological subtype. There were 95 (54.0%) patients with negative expression for programmed cell death ligand 1 (PD-L1). After progressive disease, 92 (52.3%) patients reused ICI-based treatment after progressive disease. Median PFS2 was 3.6 months [95% confidence interval (CI): 2.8-4.4]. Longer PFS2 was observed in patients with PD-L1 positive expression [hazard ratio (HR) =0.672, 95% CI: 0.477-0.947, P=0.023] or PFS ≥6 months in initial immunotherapy (HR =0.543, 95% CI: 0.358-0.824, P=0.004). Besides, patients switching to new ICI-based treatments without radiotherapy gained better PFS2 compared with patients receiving prior regimens (P=0.019). Conclusions: PD-L1 positive expression, and longer PFS in initial immunotherapy would be good prognostic factors for NSCLC patients undergoing STAP on first immunotherapy. Besides, compared with original regimen, changing ICI would prolong PFS2 for NSCLC patients reusing ICI.
