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.

Abstract

An 81-year-old immunocompetent patient with bronchiectasis and refractory Mycobacterium abscessus lung disease was treated for 6 months with a three-phage cocktail active against the strain. In this case study of phage to lower infectious burden, intravenous administration was safe and reduced the M. abscessus sputum load tenfold within one month. However, after two months, M. abscessus counts increased as the patient mounted a robust IgM- and IgG-mediated neutralizing antibody response to the phages, which was associated with limited therapeutic efficacy.
