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

Cryptosporidium parvum is a protozoan parasite that causes severe diarrheal illness in children and each year nearly 50,000 children under age 5 die due to the disease. Despite tremendous research efforts, there remains a lack of effective therapies and vaccines. Novel inhibitors against N-myristoyltransferase of C. parvum (CpNMT) are potential starting points towards the development of effective therapies. In quest of promising selective CpNMT inhibitors, structure guided modifications of compound 1 (2-chloro-5-(ethyl-phenyl-sulfamoyl)-N-[2-(2-oxo-pyrrolidin-1-yl)-phenyl]-benzamide) were performed. The resulting compounds were evaluated for selective inhibition of CpNMT over the host enzyme HsNMT1. Compounds 11e and 11f exhibited good inhibition, with IC
