Air pollution and respiratory diseases in conurbated cities in the state of São Paulo.

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
objectiveTo estimate the association between exposure to particulate matter with less than 10u of aerodynamic diameter (PM10) and hospital admissions due to acute respiratory diseases in children.
methodsThis is an ecological time series study with data on hospitalizations for respiratory diseases in children living in the conurbated cities of Taubaté, Tremembé, and Pindamonhangaba located in the Vale do Paraíba in São Paulo. Hospital admission data refer to the period between January 1, 2016 and December 31, 2019. Information on hospital admissions was obtained from the DATASUS database, and concentration values (μg/m3) of the pollutant PM10, temperature, and humidity relative air were obtained from the Environmental Company of the State of São Paulo. Negative binomial regression was used. Population attributable fraction and hospitalization costs were estimated.
resultsA total of 1,291 hospitalizations were identified in the conurbated municipalities with a daily average of 0.88 standard deviation (±) 1.06, varying between 0-7 hospitalizations. Significant exposures to PM10 can be observed at all lags, except the four-day lag (Lag 4). The total cost of hospitalizations was around US$ 800,000.00 and the excess number of hospitalizations (135) represented an expense of around US$ 80,000.00.
conclusionsStudies with conurbated cities are easily applicable, extending the study area. The results reinforce the harmful role of exposure to air pollutants in children's health.
