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
ObjectivePost-lumbar puncture headache is a common complication following lumbar puncture. Although several risk factors have been established, the role of low body mass index remains controversial. This study aimed to evaluate the association between body mass index and post-lumbar puncture headache in Chinese adults undergoing lumbar puncture.MethodsIn total, 499 patients who underwent lumbar puncture at the Department of Neurology between January 2022 and March 2024 were enrolled. Data on demographic characteristics, blood pressure, lumbar puncture history, and cerebrospinal fluid parameters were collected. Univariate and multivariate logistic regression models were employed to assess the relationship between body mass index and post-lumbar puncture headache. Subgroup analyses were conducted to evaluate the consistency of this association across sex, age, blood pressure, cerebrospinal fluid volume, and cerebrospinal fluid protein levels.ResultsPost-lumbar puncture headache occurred in 13% (65/499) of patients; among these, 63.1% were female. Compared with those without post-lumbar puncture headache, those with a headache were younger (
