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
purposeThis study's objective was to investigate barometric pressure changes that are most strongly associated with symptom exacerbations in shunted hydrocephalus patients. To achieve this, we conducted in-depth analysis of hospital encounter data and examined their correlation with variations in sea level pressure (SLP). Ultimately, our findings may inform hydrocephalus management strategies by identifying potential environmental triggers, reducing unnecessary hospital visits, and guiding the future design of CSF diversion technologies that are more responsive to external conditions.
methodsWe conducted a retrospective analysis of the daily hydrocephalus encounters census of a tertiary children's hospital and compared it with weather parameters, including fluctuations in SLP as measured in 8-h intervals, maximum daily rate of change, daily minimum SLP, and daily mean SLP. Data was analyzed in a univariate and multivariable Poisson generalized linear models, and census was compared to weather fluctuations on the day of encounter, the following day, and 2 days afterward.
resultsIn univariable analysis, hydrocephalus encounters were associated with the daily maximum rate of change, daily maximum SLP, daily minimum SLP, and daily mean SLP. These associations maintained 1 day and 2 days after the hospital encounters. In multivariate analysis, the daily maximum SLP and daily minimum SLP were associated with patient encounters both 1 and 2 days after the analyzed census date. Associations were also observed between daily minimal SLP, daily maximum SLP, and maximum daily 8-h SLP.
conclusionThis study documents an association between fluctuations in atmospheric pressure and daily hydrocephalus census at a single tertiary medical center. Weather-related influences should be considered when evaluating shunt malfunction in patients with chronic shunted hydrocephalus.
