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

introductionImmune checkpoint inhibitors (ICIs) greatly improved outcomes of stage IV non-small cell lung cancer (NSCLC) in randomized clinical trials. Limited data exists regarding the survival improvement of ICI use at the population level.

methodsClinical data of patients with pathologically confirmed stage IV NSCLC diagnosed in 2013 and 2017 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Survival outcomes were compared before and after ICI use to assess the survival improvement in the immunotherapy era in the real world.

resultsA total of 19,433 patients with stage IV NSCLC were included. Being female, age < 60 years, of American Indian and Asian or Pacific Islander race, married, non-squamous histology, without bone, brain, or liver metastases, and receiving chemotherapy were significantly associated with better prognosis in multivariable analyses. Propensity score matching (PSM) based on associated factors resulted in 8743 patients each in the non-immunotherapy and immunotherapy groups (1:1 ratio). After PSM, both overall survival (OS) (p < 0.001) and cancer-specific survival (CSS) (p < 0.001) were significantly improved in the immunotherapy group. The median OS (mOS) was 6.0 months in the non-immunotherapy group and 8.0 months in the immunotherapy group. The 1-, 2-, and 3-year OS rate was 29.0%, 14.2%, and 8.5% in the non-immunotherapy group, and 37.8%, 23.5%, and 16.7% in the immunotherapy group, respectively. Patients who were male, under 60 years old, married, white, had adenocarcinoma, had no bone or liver metastases, and received chemotherapy or radiation therapy were more likely to benefit from immunotherapy.

conclusionsSurvival outcomes of patients with stage IV NSCLC were significantly improved in the immunotherapy era. Population-level benefits of survival varied among subgroups, and not all the increase in OS meant a clinically meaningful benefit.
