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
BACKGROUND AND
objectiveTo assess whether switching valve type or valve brand during shunt revision affects clinical outcomes in pediatric patients with hydrocephalus.
methodsPatients at two centers who were younger than 26 years of age, underwent a cerebrospinal fluid (CSF) shunt revision involving a valve change, were alive at discharge, and had at least one documented clinical follow-up within 30 days were retrospectively reviewed. Patients who were implanted with a different valve type (fixed vs programmable) or brand during the shunt revision were compared to those who maintained the same valve type or brand. The rates of shunt obstruction, infection, overdrainage, reoperation, readmission, and other complications were analyzed.
resultsFifty-five patients undergoing 67 shunt revisions involving the valve met the inclusion criteria. Short-term (30-day) complication profiles were similar (p = 0.626) when the valve was replaced with another valve of the same type (n = 31) versus when a different type was implanted (n = 36). Among patients for whom the same valve type was maintained, there were no significant differences in postoperative complications when the fixed-pressure valve brand was changed (n = 7) compared to when the same brand was replaced (n = 12) (p = 0.678). Changing the programmable valve brand (n = 6) resulted in a significantly lower rate of complications (p = 0.025), specifically fewer frequent shunt obstructions (p = 0.025), compared to when the same programmable valve brand was replaced (n = 11).
conclusionIn this two-center cohort of shunt revisions involving the valve, changing the valve type or brand was not associated with differences in early (30-day) complication rates. A significant trend toward fewer complications after changing the programmable valve brand was observed in a small subgroup and should be interpreted as hypothesis-generating. Larger, longer-term studies are needed to determine the impact of valve choice on shunt survival and long-term outcomes.
