Prediction of patients with a tumor proportion score > 50% who do not respond to first-line monotherapy with pembrolizumab.
Observational study in BMC cancer, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 2 of them syntheses that pooled 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.
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
backgroundPembrolizumab is effective as first-line therapy against advanced non-small cell lung cancer (NSCLC) in patients with programmed death ligand-1 (PD-L1) expression levels ≥50% [1]. However, it is not effective in all patients, and the factors predicting responses among this population remain unknown.
methodsWe retrospectively analyzed patients with NSCLC and a PD-L1 tumor proportion score (TPS) > 50%, who received first-line monotherapy with pembrolizumab from February 1, 2017 to April 30, 2018. The study included 11 hospitals, which participated in the Hanshin Oncology clinical Problem Evaluation group (HOPE). We analyzed the differences between responders and non-responders in terms of age, sex, performance status score, degree of progression, histological type, smoking history, expression of PD-L1, use of steroids prior to treatment, metastasis site, and laboratory data.
resultsA total of 205 patients were included in this study. Of those, 108 patients exhibiting complete or partial response were defined as responders. Those exhibiting progressive disease (N = 52) were defined as non-responders. In the univariate analysis, Eastern Cooperative Oncology Group performance status score ≥ 2 (p = 0.0832), stage IV disease or recurrence (p = 0.0487), PD-L1 TPS 50-89% (p = 0.0657), use of steroids prior to the administration of pembrolizumab (p = 0.0243), malignant pleural effusion (p = 0.0032), and baseline C-reactive protein (CRP) levels > 1.0 mg/dL (p = 0.0390) were significantly associated with non-response to treatment. In the multivariate analysis, use of steroids prior to the administration of pembrolizumab (odds ratio [OR]: 5.86; 95% confidence interval [CI]: 1.32-31.8; p = 0.0200), malignant pleural effusion (OR: 2.68; 95% CI: 1.15-6.35; p = 0.0228), and baseline CRP > 1.0 mg/dL (OR: 2.17; 95% CI: 1.03-4.68; p = 0.0402) were significantly associated with non-response to treatment.
conclusionIn real-world patients with NSCLC and a PD-L1 TPS ≥50%, use of steroids prior to treatment, malignant pleural effusion, and baseline CRP levels > 1.0 mg/dL reduced the response of first-line monotherapy with pembrolizumab.
