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

backgroundUrinary calculi is a common condition characterized of high incidence and high recurrence rate. For a long time, increased water intake has been the main preventive measure for the disease and its recurrence.

objectivesTo access the effectiveness of increased water intake for the primary and secondary prevention of urinary calculi. SEARCH STRATEGY: Relevant RCTs were identified by electronic and documental searches of MEDLINE, EMBASE, the Chinese Biomedical Disk and the Cochrane Central Register of Controlled Trials. No language restriction was applied. Date of last search: May 2004. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs of increased water intake for the prevention of urinary calculi and its recurrence. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) for dichotomous outcomes or weight mean difference (WMD) for continuous data with 95% confidence intervals (CI). MAIN

resultsNo trials of increased water intake for the primary prevention of urinary calculi met the inclusion criteria. One trial with 199 patients provided results of increased water intake for the recurrence of urinary calculi. The recurrence rate was lower in the increased water intake group than that of the no intervention group (12% versus 27%, P = 0.008, RR = 0.45, 95% CI 0.24 to 0.84). The average interval for recurrences was 3.23 +/-1.1 years in increased water intake group and 2.09 +/- 1.37 years in the no intervention group (P = 0.016, WMD = 1.14, 95% CI 0.33 to 1.95). REVIEWERS'

conclusionsThe evidence from only one trial indicates that increased water intake reduces the risk of recurrence of urinary calculi and prolongs the average interval for recurrences. However further research is required. Due to the lack of appropriate RCTs, no conclusions can be drawn on increased water intake for the primary and secondary prevention of urinary calculi.
