Clinical Effectiveness of Calcium Oxalate Stone Treatments.
Review in American journal of nephrology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
introductionLowering kidney stone risk and urine calcium oxalate supersaturation is a primary clinical focus for kidney stone prevention and can be achieved with multiple strategies. Common strategies include advice to increase fluid intake, restrict dietary sodium, or prescribing a thiazide-type diuretic. We investigated how physicians make these decisions in real-world practice and evaluate their efficacy based on 24-h urine collections.
methodsWe reviewed medical charts for 203 kidney stone formers with idiopathic calcium stones from University of Chicago Kidney Stone Clinic between 2005 and 2020. Patients had three 24-h urines before an initial pre-treatment clinic visit and one follow-up 24-h urine. We analyzed changes in urine composition based on treatment advice using t tests and ANOVA.
resultsPatients who received advice to increase fluid intake had lower urine volume at baseline (1.5 vs. 2.5 L/day, p < 0.001) and larger increase in urine volume at follow-up (0.6 vs. 0.1 L/day, p < 0.001) compared to those who did not receive the advice. Patients who were advised to restrict dietary sodium had a higher urine sodium at baseline (208 vs. 139 mEq/day, p < 0.001), a larger reduction in urine sodium (-28 vs. 13 mEq/day, p = 0.002), and larger reduction in urine calcium (-74 vs. -28 mg/day, p = 0.005) compared with those not advised to restrict dietary sodium. Patients started on a thiazide had a higher baseline urine calcium (281 vs. 213 mg/day) and larger reduction in urine calcium (-83 vs. -9 mg/day, p < 0.001) compared with patients not started on a thiazide. In combination, thiazide prescriptions with dietary sodium restriction reduced urine calcium by 99 mg/day and reduced calcium oxalate supersaturation from 8.0 to 5.5 and calcium phosphate supersaturation from 1.4 to 1.0.
conclusionProviders use 24-h urine data to guide treatment strategy decisions. These strategies achieved the intended effects on urine composition and lowered kidney stone risk.
