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
objectivesThe COVID-19 pandemic affected mental health worldwide, including obsessive-compulsive symptoms (OCS) and, specifically, contamination-related OCS (C-OCS). This study aimed to map these symptoms' trajectories over four years, thus providing the longest known observational timeline of OCS during and after a pandemic. Longitudinal data on OCS spanning this period offer the rare opportunity to examine how external crises intersect with symptom trajectories over time, offering insights into patterns of symptom fluctuation and remission.
designWe conducted a longitudinal panel study with 1,214 participants from the German general population assessed at the onset of the pandemic (T1), three months later (T2) and 12 months after T1 (T3), followed by annual assessments (T4, T5, T6).
methodsWe measured OCS and C-OCS using the Obsessive-Compulsive Inventory-Revised and calculated mixed-effect models for repeated measurements.
resultsAnalyses indicated a significant but declining increase in OCS from T1 to T2, T3 and T4 (d = -.11 to -.05), with symptoms returning to baseline levels during annual assessments at T5 (d = -.02) and T6 (d = .03). By contrast, C-OCS consistently and significantly decreased at each timepoint, indicating a steady reduction in symptom severity over the assessment period (d = .12 to .46).
conclusionThe initial OCS spike reflects stress and uncertainty in the population, while the steady C-OCS improvement may be due to the normalization of hygiene practices over time. These patterns highlight the impact of pandemic-related health management on C-OCS. Factors affecting the general population that are linked to these symptoms can contribute to an individual's deterioration (for example promotion of hygiene practices). Understanding these dynamics contributes to a better understanding of C-OCS and associated risk factors.
