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

backgroundUreaplasmas have been inconsistently associated with nongonococcal urethritis (NGU). We evaluated the association of the newly differentiated species Ureaplasma urealyticum (UU) and Ureaplasma parvum (UP) with NGU using 2 separate control groups.

methodsCase patients were men who attended a sexually transmitted disease (STD) clinic in Seattle, Washington, during the period 2007-2009 with NGU (defined as visible urethral discharge and/or ≥5 polymorphonuclear neutrophils per high-powered field; n = 329). Control subjects were STD clinic attendees (n = 191) and emergency department (ED) attendees (n = 193) without NGU. Polymerase chain reaction assays detected UU and UP in ureaplasma culture-positive urine. Multivariable logistic regression was used to assess the associations of UU and UP with NGU.

resultsUU was only marginally associated with NGU in aggregate multivariable analyses, irrespective of control group (adjusted odds ratio [aOR](STD-control), 1.6 [95% confidence interval {CI}, 0.9-2.8]; aOR(ED-control), 1.7 [95% CI, 0.97-3.0]). This association was significantly stronger when analyses were restricted to men with fewer lifetime sex partners (<10 vaginal partners: aOR(STD-control), 2.9 [95% CI, 1.2-6.7]; aOR(ED-control), 3.2 [95% CI, 1.3-7.6]; <5 vaginal partners: aOR(STD-control), 6.2 [95% CI, 1.8-21.0]; aOR(ED-control), 5.2 [95% CI, 1.3-20.2]). UP was not positively associated with NGU overall or among subgroups.

conclusionsThe absence of an association of UU with NGU among men with more lifetime sex partners suggests that adaptive immunity may attenuate the clinical manifestation of UU infection. Similar relationships were not observed with UP, which suggests that it is not a urethral pathogen.
