Clinically applicable cases of anti-programmed cell death protein 1 immunotherapy for colorectal cancer patients.
Article in Surgery today, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
We investigated the prevalence and characteristics of defective mismatch repair (dMMR) in colorectal cancer (CRC) patients who would potentially benefit from anti-programmed cell death protein 1 (PD-1) immunotherapy. Medical records were obtained and reviewed for 1147 patients who underwent surgical resection of stage I-IV CRC, in whom universal screening for Lynch syndrome using immunohistochemistry for MMR proteins had been undertaken. The molecular characteristics of dMMR CRCs were also investigated. Defective MMR accounted for 5.2% of stage I-IV CRC patients, including 12 (1.0% of all CRC patients) who had stage IV disease or recurrence after curative resection (n = 6 each). These 12 patients included patients with LS (n = 3) and Lynch-like syndrome (n = 1). Defective MMR tumors were predominantly located in the right-sided colon (P < 0.01). Approximately 1% of stage I-IV CRC patients could potentially benefit from anti-PD-1 immunotherapy, while one-third would require genetic counseling and/or MMR gene testing.
