Does Pollen Trigger Urological Chronic Pelvic Pain Syndrome Flares? A Case-Crossover Analysis in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network.
Article in The Journal of urology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01098279 (Multidisciplinary Approach to the Study of Chronic Pelvic Pain), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
purposeWe sought to determine whether pollen triggers urological chronic pelvic pain syndrome flares. MATERIALS AND
methodsWe assessed flare status every 2 weeks for 1 year as part of the Multidisciplinary Approach to the Study of Chronic Pelvic Pain case-crossover analysis of flare triggers (NCT01098279). Flare symptoms, flare start date and exposures in the 3 days before a flare were queried for the first 3 flares and at 3 randomly selected nonflare times. These data were linked to daily pollen count by date and the first 3 digits of participants' zip codes. Pollen count in the 3 days before and day of a flare, as well as pollen rises past established thresholds, were compared to nonflare values by conditional logistic regression. Poisson regression was used to estimate flare rates in the 3 weeks following pollen rises past established thresholds in the full longitudinal study. Analyses were performed in all participants and separately in those who reported allergies or respiratory tract disorders.
resultsAlthough no associations were observed for daily pollen count and flare onset, positive associations were observed for pollen count rises past medium or higher thresholds in participants with allergies or respiratory tract disorders in the case-crossover (OR 1.31, 95% CI 1.04-1.66) and full longitudinal (RR 1.23, 95% CI 1.03-1.46) samples.
conclusionsWe found some evidence to suggest that rising pollen count may trigger flares of urological chronic pelvic pain syndrome. If confirmed in future studies, these findings may help to inform flare pathophysiology, prevention and treatment, and control over the unpredictability of flares.
