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

purposeTo evaluate the association between being underweight and shockwave lithotripsy outcomes.

methodsThis retrospective two-centre cohort study conducted in Japan involved 597 patients diagnosed with a single urinary tract calculus based on computed tomography and who underwent shockwave lithotripsy between 2006 and 2016. We divided the patients into four groups based on their body mass index (underweight, ≤  18.4; normal weight, 18.5-24.9; overweight, 25-29.9; obese,  ≥  30 kg/m

resultsOf the 597 patients, 25 (4.2%) were underweight and 34 (5.7%) were obese. After adjusting for age, sex, calculus localisation, maximum stone length, mean stone density, and skin-to-stone distance, being underweight showed a significantly negative association with success of single-session shockwave lithotripsy (odds ratio 0.25, 95% confidence interval 0.09-0.69) compared to being normal weight.

conclusionsThis study showed the negative impact of being underweight on the outcomes of shockwave lithotripsy in patients with upper urinary tract calculi. This finding provides a novel viewpoint regarding the body mass index and should aid improved treatment selection for patients with upper urinary tract calculi.
