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

BACKGROUND/

aimChemoimmunotherapy has improved overall survival in patients with extensive small-cell lung cancer (SCLC). However, the backgrounds of patients enrolled in clinical trials tend to differ from those of patients treated in clinical practice, and the effectiveness of chemoimmunotherapy may be unclear in some populations, including patients with poor performance status. This study aimed to evaluate the effectiveness of chemoimmunotherapy for SCLC patients in clinical practice while focusing on several subgroups. PATIENTS AND

methodsWe retrospectively analyzed the data of SCLC patients who received chemoimmunotherapy or chemotherapy. The association between chemoimmunotherapy and overall survival was evaluated by adjusting for patient backgrounds using the Cox proportional hazards model, followed by a subset analysis.

resultsThe chemoimmunotherapy and chemotherapy groups included 43 and 71 patients, respectively. The Cox proportional hazards model showed that chemoimmunotherapy was significantly associated with improved overall survival (hazard ratio=0.47, 95% confidential interval=0.26-0.83). Furthermore, subgroup analysis showed that overall survival was significantly improved in patients with good performance status, lower neutrophil/lymphocyte ratio, and no liver metastases. However, overall survival with chemoimmunotherapy was similar to that with chemotherapy and was less than 12 months in patients with a poor performance status or higher neutrophil/lymphocyte ratio.

conclusionChemoimmunotherapy was significantly associated with improved overall survival in clinical practice. However, the effectiveness was equivocal in SCLC patients with a poor performance status or higher neutrophil/lymphocyte ratio.
