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

Objectives: Twenty-four-hour urine collections are obtained as part of the metabolic workup for nephrolithiasis to identify modifiable abnormalities for stone prevention. We sought to discern trends in the prevalence of abnormalities based on body mass index (BMI) (kg/m Material and Methods: All unique Litholink™ 24-Hour Urine outcomes for nephrolithiasis prior to medical or dietary therapy obtained at our institution between 2004 and 2020 were retrospectively reviewed. Patients with anthropometric data were classified according to body mass index (BMI) as underweight (<18.5), normal (18.5-25), overweight Results: A total of 1372 patients were included. The mean age was 56 Conclusions: Body weight differences are associated with different risk profiles on 24-hour urine collection. Obese, and to a letter degree, underweight patients are more likely to harbour metabolic derangements on a 24-hour urine analysis compared to patients with normal BMI, thus underscoring the importance of directed medical therapy for stone formers.
