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

objectiveImmune therapy with the PD1 inhibitor pembrolizumab has been approved to treat unresectable/metastatic solid tumours exhibiting mismatch repair (MMR) deficiency. Lynch syndrome (LS), caused by autosomal dominant germline mutations of a MMR gene, predisposes to the development of MMR-deficient cancers. We report a case of

conclusionTesting for MMR protein expression is recommended for each tumour in patients with LS, especially pancreatic, as discordant results may have profound effects on treatment opportunities. To our knowledge, this is the first documented case of MMR-intact PDAC in a patient with
