Continuation of same programmed death-1 inhibitor regime beyond progression is a novel option for advanced gastric cancer.
Article in BMC cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundGastric cancer is a significant global malignancy with poor prognosis. Although the emergence of immune checkpoint inhibitors (ICIs) prolonged the duration of survival, resistance and progression are inevitable. We aim to evaluate the effectiveness of programmed death-1 (PD-1) inhibitors in immunotherapy beyond progression (IBP).
methodWe divided the advanced gastric cancer patients who received two lines immunotherapy into same regimen group (with same PD-1 inhibitor regime after IBP) and different regimen group (with different PD-1 inhibitor regime after IBP). Statistical analysis conducted to compare patient characteristics and evaluate survival differences between groups.
resultThe clinical outcome analysis showed that the same PD-1 inhibitor regime seemed to exhibit a higher disease control rate (DCR) (51.8% vs. 29.2%, P = 0.062), significantly prolonged progression-free survival 2 (PFS2) (162 vs. 75 days, P = 0.001) and overall survival (OS) (312 vs. 166 days, P = 0.022) when compared with those of cross line. In the multivariate analysis, when using different regimen group as reference, the same regimen group was found to be independently associated with improved PFS2 [hazard ratio (HR) = 0.467, 95% confidence interval (CI): 0.267-0.816, P = 0.008] and OS (HR = 0.508, 95%CI: 0.278-0.927, P = 0.027).
conclusionContinuation of the same type of PD-1 inhibitor regime in IBP shows clinical benefits and represents a promising therapeutic approach.
