Early presentation of pembrolizumab-associated pneumonitis.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Pembrolizumab is a selective anti-PD-L1 humanised monoclonal antibody approved by the Food and Drug Administration for treating multiple cancers, including cervical cancer, non-small cell lung cancer (NSCLC), renal cell carcinoma, bladder cancer, and squamous head and neck cancer. Pneumonitis is a rare but known complication of pembrolizumab treatment for NSCLC. The median time frame of its appearance is 2.8 months. However, we present a case of pneumonitis appearing within 48 hours. The patient presented with rapidly progressive respiratory failure, and imaging demonstrated diffuse bilateral patchy involvement of the upper lung lobe and pre-hilar regions, which likely indicate pneumonitis. Because of likely grade 3 pneumonitis, he was treated with steroids and showed immediate improvement of symptoms. Repeated CT imaging showed resolution of bilateral patchy infiltrates. He was discharged to the rehabilitation unit. Rapid recognition of pneumonitis as a side effect of pembrolizumab is important because early treatment can help prevent respiratory failure and possible death.
