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

backgroundDifferences of more than 30% have been observed between the results of vaccine coverage surveys and routine vaccine coverage data. In the context of the organization and operation of the health system, the study focused on investigating explanatory factors for over-reporting.

methodsThis was a mixed-method, cross-sectional, and analytical study. Over-reporting of routine immunization data was defined as a discrepancy of ≥ 10% points between routine data and survey data or recount data (standards) for the Penta3 vaccine. Data were collected by questionnaire from 117 health centers, 30 health zone offices, and 13 provincial health offices. Bivariable and multivariable analyses (α = 5%) were used to find factors influencing over-reporting. Data from 30 in-depth interviews were collected to complement quantitative data.

resultsThe phenomenon of over-reporting of routine immunization data was verified in the health zones (90% or 77%) and health centers (43%) surveyed in 2019 and 2020. At the health zone level, six explanatory factors emerged. The most significant tree variables being the pressure exerted on managers to achieve pre-established annual targets (p = 0.016), the availability of data collection tools (p = 0.010) and bearer message for manual transport of reports (p = 0.031). At the health center level, seven factors were found, and the four most significant were: availability of a cell phone (p = 0.002), existence of table or graph for coverage monitoring (p = 0.003), availability of a computer in the health center (p = 0.007) and designated health data collector (p = 0.015). Qualitative data revealed three over-reporting practices: deliberate inflation of vaccine delivery figures, readjustment of expected target population figures, and occasional errors in data transcription.

conclusionOver-reporting is essentially generated by providers. Solving this problem requires lifting the pressure exerted on managers at different levels of the health system, making data management more secure, and qualifying the staff responsible for managing immunization data.
