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

Gradenigo-Lannois syndrome or petrous apicitis is an uncommon but a morbid complication of otitis media. Traditionally treated by surgery, recent advances in imaging and antibiotics have favoured a more conservative approach. Although pyogenic organisms are the leading aetiological agent, petrous apicitis due to Koch's bacilli is not rare. We report two cases of tubercular petrositis presenting as Gradenigo's syndrome with triad of ear discharge, deep-seated retro-orbital pain and diplopia. The first patient represented a mixed infection with pyogenic organism and tuberculosis, which was successfully treated with antibiotics and antitubercular therapy. The second patient showed an acute presentation of Gradenigo's syndrome with chronic otitis media having contact with an active tuberculosis case and showed dramatic response with antitubercular treatment. Tubercular petrous apicitis must be suspected and diagnosed promptly as only specific treatment will lead to symptomatic resolution and avoid complications.
