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
Background: The combination of an anti-programmed death-ligand 1 (PD-L1) antibody with etoposide and either carboplatin or cisplatin (platinum-etoposide) has become the first-line treatment for patients with extensive-stage small-cell lung cancer (ES-SCLC). Although previous studies have examined the relationship between geriatric assessments and treatment efficacy, the association with treatment tolerability in elderly patients with ES-SCLC remains insufficiently understood. We aimed to evaluate the association between low body mass index (BMI)-a component of geriatric assessment-and treatment tolerability. Methods: We conducted a retrospective analysis of patients aged ≥65 years with ES-SCLC who received anti-PD-L1 antibody plus platinum-etoposide at a single center between August 2019 and April 2024. Tolerability was defined as the completion of four cycles of anti-PD-L1 antibody combined with platinum-etoposide. We also assessed treatment efficacy and safety profiles. Results: A total of 71 patients were included, with a median age of 73 years (range: 65-91 years). Of these, 51 patients (72%) were male, and 54 (76%) had an Eastern Cooperative Oncology Group performance status (ECOG-PS) of 0 or 1. Sixteen patients (23%) showed a low BMI (<19 kg/m2), whereas 55 (77%) showed a non-low BMI. Tolerability was achieved in 8 patients (50%) with low BMI compared with 44 patients (80%) with non-low BMI. There were no significant differences in overall survival, progression-free survival, or the incidence of grade ≥3 adverse events among the two groups. In multivariate analysis, low BMI and ECOG-PS ≥2 were independently associated with reduced treatment tolerability [odds ratio (OR): 0.24, 95% confidence interval (CI): 0.06-0.88, P=0.03; OR: 0.13, 95% CI: 0.04-0.48, P<0.01, respectively]. Conclusions: Low BMI and poor performance status were independently associated with decreased tolerability to anti-PD-L1 antibody combined with platinum-etoposide in elderly patients with ES-SCLC. These findings underscore the importance of incorporating geriatric assessments into treatment decision-making for this population.
