Incidence risk of PD-1/PD-L1-related pneumonia and diarrhea in non-small cell lung cancer (NSCLC) patients: a systematic review and meta-analysis of randomized controlled trials.
Synthesis in European journal of clinical pharmacology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis 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
backgroundProgrammed cell death-1 (PD-1) and programmed cell death ligand-1(PD-L1) inhibitor therapy have been approved for the treatment of many cancers, although their incidence of some side effects was high. We aim to fully investigate the incidence risk of PD-1/PD-L1 inhibitors-related pneumonia and diarrhea in NSCLC patients, as well as treatment-related deaths.
methodsPubMed, Medline, Cochrane Library, and Clinical trials.gov databases were searched up to Sep 17, 2020, for clinical trials of PD-1 inhibitors and PD-L1 inhibitors in the treatment of NSCLC. Randomized controlled trials and their references were screened.
resultsSeventeen trials were included in our meta-analysis, including 11,363 patients. PD-1/PD-L1 inhibitors significantly increased the risk of developing all-grade and high-grade (grade ≥ 3) pneumonia (risk ratio [RR] = 2.28; 95% CI: 1.39-3.76; P < 0.01; RR = 2.38; 95% CI: 1.72-3.29; P < 0.01, respectively). The use of PD-1/PD-L1 inhibitor did not increase the risk of developing all-grade and high-grade diarrhea (RR = 0.79; 95% CI: 0.62-1.01; P = 0.06; RR = 0.96; 95% CI: 0.70-1.31; P = 0.78, respectively). There was no significant difference between the rate of death in PD-1 and PD-L1 inhibitors (P = 0.079).
conclusionThese data suggest that PD-1/PD-L1 inhibitors significantly increase the risk of all-grade and high-grade pneumonia in NSCLC patients and PD-1/PD-L1 monotherapy increases the risk of all-grade pneumonia in NSCLC patients compared to PD-1/PD-L1 inhibitor combination regimens. Physicians should pay more attention to NSCLC patients who treated with PD-1/PD-L1 inhibitors.
