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

objectiveTo define 'chronic' urinary tract infection (UTI) by reviewing current published research that employs this term.

methodsWe systematically searched Medline and Embase for studies covering all aspects of human UTI. For comparison, current urological and infectious disease guidelines were also reviewed.

resultsThe electronic search yielded a total of 2175 articles, of which 154 were eventually included for data extraction. Of these, six studies presented a definition of chronic UTI within the text. The definitions were highly incongruent among studies and often identical to the current definition of 'recurrent' UTI.

conclusionChronic UTI is an undefined term, which has nevertheless been increasingly used in the past 15 years. Chronic UTI does not represent a distinct clinical or microbiological condition that justifies its use as medical diagnosis.
