Pattern of vaccination delivery around COVID-19 lockdown in Nigeria.

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
COVID-19 pandemic has affected the world, including developing countries in various aspects. This pandemic might have severe consequences in terms of population health, especially in places where the health system is already weak. Using the health facility-level data over time, we evaluated the impact of COVID-19 lockdown on the vaccination service delivery in Nigeria. The lockdown was announced on March 30, 2020 and was effective until May 4, 2020. Compared to the quantity of vaccinations administered in March 2020, the quantity was significantly reduced during April 2020. The quantity was further reduced during May 2020. However, from June onwards, the quantity of vaccination administered has recovered. We observed that, although the lockdown reduced the quantity of vaccination administered significantly, it quickly recovered soon after the lockdown was relaxed.
