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

objectiveDetermine whether a 1-hour pad test at discharge can identify continence status within 120 days of obstetric vesicovaginal fistula (VVF) repair.

designProspective cohort study.

settingFistula Care Centre in Lilongwe, Malawi. POPULATION: Women with VVF who underwent repair between January 2012 and December 2014.

methodsData on demographics, obstetric history, physical exam findings, operative management, postoperative findings, and follow up evaluations were collected on women with VVF repair.

main outcome measuresSensitivity, specificity, positive and negative predictive values (PPV and NPV), and a receiver operating curve (ROC) were calculated to assess the utility of using a discharge pad test at three thresholds to identify women likely to be continent at follow up.

resultsAfter VVF repair, 346 women had a 1-hour pad test performed at the time of hospital discharge and completed follow up within 120 days of repair. Of these, 79.8% (n = 276) were completely continent, whereas 20.2% (n = 70) had some degree of incontinence. The sensitivity and specificity of a negative 1-hour pad test at predicting continence is 68.1% and 82.9%, respectively. With this prevalence, a negative pad test at a 1.5-g threshold demonstrates a high predictive value (PPV = 94.0%, 95% CI 90.0-96.9) in detecting women with continence after repair.

conclusionsAt the 1.5-g threshold, a negative pad test at discharge identifies 94% of women who will remain continent after VVF repair. Adding the pad test to fistula care can identify women who are likely to remain continent and may not need further therapies in settings where resources are limited and follow up after repair is difficult. TWEETABLE ABSTRACT: A negative pad test after repair is associated with continued continence at follow up.
