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
purposeThe first weeks of the COVID-19 pandemic were a period of stress, uncertainty, and major disruptions due to the lockdown. We aimed to study the variation in psychiatry-related and addiction-related visits to the emergency department during the first COVID-19 lockdown compared with pre-lockdown periods.
methodsWe examined psychiatry-related and addiction-related visits to the emergency department of Calais Hospital before and during the lockdown in France. We analyzed the differences between the periods by (1) comparing means and medians, (2) performing modeling using a generalized linear mixed model (GLMM) and an autoregressive integrated moving average model with exogenous variables (ARIMAX), and (3) identifying breakpoints in the time series.
resultsFor psychiatry-related visits, the mean was higher before the lockdown (4.05) compared to during the lockdown (2.36, p < 0.001). A negative slope of -0.55 (p < 0.001) was found with the GLMM, confirming the decrease. The ARIMAX yielded similar results (slope: -1.74, p < 0.001). There was a breakpoint in the time series 11 days before the lockdown. For addiction-related visits, the mean was lower before the lockdown (0.8) compared to during the lockdown (1.46, p = 0.044). The GLMM found a positive slope of 0.62 (p = 0.005), confirming the increase and the ARIMAX showed similar results (slope: 0.74, p < 0.001).
conclusionDuring the first weeks of the COVID-19 pandemic, psychiatry-related visits to the emergency department decreased, while addiction-related visits increased. The decrease in psychiatric visits began before the first COVID-19 lockdown.
