Toxicity profiles of immune checkpoint inhibitors for recurrent or metastatic head and neck squamous cell carcinoma: A systematic review and meta-analysis.
Synthesis in Cancer medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 3 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
backgroundImmune checkpoint inhibitors (ICIs) are widely used in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC); however, the toxicity profiles are inconclusive.
methodsClinical trials evaluating ICIs for R/M HNSCC were searched from online databases. The characteristics of the studies and the results of incidences of any grade treatment-related adverse events (trAEs), grade three or more trAEs, treatment-related deaths, trAEs leading to discontinuation of treatment, and specific trAEs were extracted.
resultsTwenty studies with 3756 patients were included. The pooled incidences of any grade trAEs, grade three or more trAEs, treatment-related deaths, trAEs leading to discontinuation of treatment for overall population were 62.07% (95% CI, 59.07%-65.02%), 13.82% (95% CI, 11.23%-16.62%), 0.39% (95% CI, 0.15%-0.71%), 3.99% (95% CI, 2.36%-5.95%), respectively. Programmed cell death protein 1 (PD-1) inhibitors monotherapy and ICIs combination therapy had significantly higher incidences of any grade trAEs (odds ratio [OR], 1.25, 95% CI, 1.05-1.49 and 1.36, 95% CI, 1.15-1.60, respectively), grade three or more trAEs (OR, 1.41, 95% CI, 1.08-1.84 and 1.79, 95% CI, 1.39-2.30, respectively), trAEs leading to discontinuation of treatment (OR, 3.98, 95% CI, 2.06-7.70 and 10.14, 95% CI, 5.49-18.70, respectively) compared with programmed death-ligand 1 (PD-L1) inhibitors monotherapy. ICIs combination therapy had a significantly higher incidence of grade three or more trAEs compared with PD-1 inhibitors monotherapy (OR, 1.27, 95% CI, 1.03-1.55); however, the incidences of any grade trAEs and trAEs leading to discontinuation of treatment were not significant different.
conclusionsOur study suggests that the incidences of grade three or more trAEs, treatment-related deaths, and trAEs leading to discontinuation of treatment are low in R/M HNSCC patients treated with ICIs. PD-L1 inhibitors monotherapy may be safer compared with PD-1 inhibitors monotherapy and ICIs combination therapy.
