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

Immune checkpoint inhibitors (ICIs) are effective for previously treated patients with advanced non-small cell lung cancer (NSCLC). However, an unconventional response pattern is sometimes encountered. A dissociated response (DR), characterized by some lesions shrinking and others growing, has been recognized with ICI treatment. In this study, we examined the characteristics and treatment outcomes of DR in previously treated NSCLC patients, receiving nivolumab monotherapy. We conducted a retrospective cohort study of previously treated patients with advanced NSCLC who received nivolumab. We assessed the tumor response of each organ using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria at the first radiologic evaluation. We investigated treatment outcome and compared overall survival using the Kaplan-Meier Method and log-rank tests. Further, we conducted the same analysis in patients who had previously received chemotherapy or tyrosine kinase inhibitor therapy in our hospital. Between April 2016 and September 2018, 107 patients who received nivolumab fulfilled the inclusion criteria. Of them, 5 (5%) patients showed a DR. There were no specific differences in characteristics between DR and non-DR cases. Patients showing DR had significantly longer overall survival than those showing concordant progressive disease (46.9 vs. 8.2 months, p = 0.038). The frequencies of DR in the ICI, chemotherapy, and tyrosine kinase inhibitor-treated cohorts were 5%, 1%, and 4%, respectively. DR was uncommon, but this presented a distinctive pattern of nivolumab response. Some patients might benefit from continuing nivolumab therapy and may achieve a longer overall survival.
