Early effects of the COVID-19 pandemic on the acute flaccid paralysis surveillance in East and Southern African countries.
Article in The Pan African medical journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionthe World health organisation (WHO) African Region reported the first confirmed COVID-19 case caused by the SARS-CoV-2 on 25
methodsa comparative analysis study design of secondary acute flaccid paralysis (AFP) surveillance data received from the East and Southern Africa sub-region countries to evaluate the effect of the COVID-19 pandemic in the AFP field surveillance for the same time period of March to December 2019 and 2020.
resultswe observed that 52.4% of second stool samples were received in the laboratory within 72 hours from March to December 2019, and only 48.1% in the same period of 2020. A 4.3% decline with a p-value of <0.0001 (95% CI, ranges from 2.326% to 6.269%). Similarly, we noted a 4.7% decline in the number of reported AFP cases in the ESA sub-region for March to December 2020 compared to the same period in 2019, a p-value of less than 0.001 (95% CI ranges from 2.785 to 6.614). For the percentage of stool adequacy, we observed a 3.37% decline for April in 2020 compared to April 2019 with a p-value of less than 0.001 (95% CI ranges from 2.059 to 4.690).
conclusionwe observed a decline in the core AFP surveillance (non polio) NP-AFP rate, and percentage of stool adequacy in countries severely affected by the COVID-19 disease. These countries implemented stringent transmission prevention measures such as lock-down and international transportation restrictions.
