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

Objective: Kidney stone disease is a relapsing disease and preventive measures are therefore of great importance. A cornerstone for adequate treatment and prevention of kidney stone recurrence is stone analysis. This pilot study aimed to evaluate whether time and different Methods: Ninety-two stone fragments from 23 kidney stone patients were allocated to four groups (Group A, direct stone analysis; Group B, dry non-transparent environment; Group C, dry transparent environment; Group D, wet non-transparent environment). Fragments from Groups B, C, and D were photographed on postoperative day (POD) 0 and POD 84 and sent for stone analysis afterwards. The objective change in appearance was assessed through the mean Euclidean distance in the Commission Internationale de l'Éclairage Results: Overall, the mean Euclidean distance was 5.52 between POD 0 and POD 84. XRD had an agreement between POD 0 and POD 84 of 98%. MCA had an agreement of 92%. The objective changes in appearance between POD 0 and POD 84 did not correlate with the diagnostic accuracy of XRD or MCA. Conclusion: The appearance of kidney stones alters over time and in different
