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

introduction and hypothesisThere is significant variability in technique for cystodistension and an international discrepancy in the role in its treatment of bladder pain syndrome (BPS). The authors evaluate the evidence base for the use of cystodistension for BPS with particular reference to patient-related outcomes.

methodsIn accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement, a prospective search and evaluation protocol was prepared and registered with the PROSPERO database (ID CRD42017053710). A review of the literature was performed using the search terms cystodistension and hydrodistension of the bladder using the PubMed database on 6 October 2016.

resultsA total of 59 papers were reviewed, but only 17 studies contained original data available for analysis from 1975 to 2016. Ten studies evaluated the outcome of cystodistension in a single arm design or used cystodistension as the control for evaluating adjunctive treatments. Seven studies evaluated cystodistension in combination with other agents or therapies. The best symptomatic responses reported a subjective improvement in 56% of men with moderate to severe prostatitis and 57% in patients with "inflammatory cystitis" respectively. There were no studies that employed a validated outcome measure, neither a questionnaire nor an analogue scale, to assess the effect of cystodistension alone.

conclusionsCystodistension is increasingly popular, despite a weak evidence base by current standards. The quality of available evidence falls below the level that would be expected of a new intervention. This review highlights the need for cystodistension to be further investigated with randomised control trials.
