1 · What the graph read from 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.

2 · The registry

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 population is under the grip of global pandemic of COVID-19. The present study analyzed relationship between meteorological parameters and COVID-19 in three major cities of Pakistan, that is, Karachi, Lahore, and Peshawar.

methodsThe impacts of heat index (HI) and ultraviolet index (UVI) over daily COVID-19 cases have examined to identify its transmission and propagation. The significance of basic reproductive number (R0), growth rate (Gr) and doubling time (Td) of COVID-19 with HI and UVI was determined.

resultsBoth indices show a significant positive correlation (at 5% significance level) to R0, Td, and Gr of COVID-19 patients. Our results showed that the minimum threshold temperature of 33 °C for HI (with a positive variation of 3 °C to 5 °C) put a significant impact on new cases.

conclusionHI and UVI impacted significantly to decline COVID-19 cases over the region.
