1 · What the graph read from 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.

2 · The registry

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

purposeThe most frequent mutation in advanced non-small-cell lung cancer (NSCLC), Kirsten rat-sarcoma viral oncogene (KRAS) is found in 20-25% of these patients' tumors. While phase III trials on therapies targeting KRAS, especially KRAS

methodsThis meta-analysis examined randomized-trial data comparing first- or second-line anti-PD-(L)1 with or without chemotherapy vs. chemotherapy alone for advanced KRAS-mutant NSCLCs. Outcome measures included overall survival (OS) and progression-free survival (PFS). Analyses were computed using the Cochrane method of collaboration for meta-analyses, with Review Manager software (RevMan version 5.3; Oxford, UK).

resultsWe analyzed 3 first-line trials (IMpower-150, Keynote-189 and Keynote-042) and 3 second-line trials (Oak, Poplar and CheckMate-057) that included 1313 NSCLCs (386 KRAS-mutant and 927 KRAS wild-type tumors). For KRAS-mutant NSCLCs, anti-PD-(L)1 with or without chemotherapy was significantly associated (hazard ratio [95% confidence interval]) with prolonged OS (0.59 [0.49-0.72]; p < 0.00001) and PFS (0.58 [0.43-0.78]; p = 0.0003) compared to chemotherapy alone. OS benefited in both first- and second-line trials. OS for patients with KRAS-mutant NSCLCs was significantly longer than that for those with KRAS wild-type tumors (p = 0.001).

conclusionsAnti-PD-(L)1 with or without chemotherapy seemed to achieve longer OS and PFS than chemotherapy alone for patients with KRAS-mutant and wild-type KRAS advanced NSCLCs, with an even greater OS benefit for the former.
