Effect of the thyroid transcription factor 1 expression and treatment discontinuation due to adverse events on progression-free survival in patients with advanced non-squamous non-small cell lung cancer treated with pembrolizumab plus pemetrexed and platinum chemotherapy: a Japanese four-hospital, retrospective study.

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
Although a significant improvement in progression-free survival (PFS) has been reported in the thyroid transcription factor 1 (TTF-1) positive patients under treatment for non-squamous non-small cell lung cancer (NS-NSCLC), including immune checkpoint inhibitor therapy, the association between TTF-1 expression and adverse event occurrence remains unclear. Therefore, this study investigated the impact of TTF-1 and its adverse events on PFS during pembrolizumab plus pemetrexed and platinum chemotherapy for NS-NSCLC. Patients who received the pembrolizumab plus pemetrexed and platinum chemotherapy from 1/1/2018 to 12/31/2022 and whose TTF-1 expression was measured were included in the study. This was a retrospective study conducted using electronic medical records. The mean age of the 79 patients was 67.5 ± 8.4 years, with 75.95% patients being male. Among them, 59.49% were TTF-1 positive. PFS comparison between TTF-1-positive and -negative patients showed a trend toward longer PFS for TTF-1 positive patients, though the results were statistically insignificant (P = 0.190). Proportional hazards analysis indicated significant PFS extension from treatment interruption, as adverse events related to cancer therapy stopped (hazard ratio [HR] = 0.32, P = 0.005) and the number of anticancer agents used (HR = 0.01, P < 0.001). Additionally, pembrolizumab plus pemetrexed and platinum chemotherapy for TTF-1-positive NS-NSCLC significantly extended PFS after treatment discontinuation as related adverse events stopped (827 vs. 210 days, P = 0.021). Measurement of TTF-1 may accordingly serve as a predictor of treatment response to the pembrolizumab plus pemetrexed and platinum chemotherapy. It may also be a predictor of patient prognosis when treatment is discontinued due to related adverse events.
