Article in Journal of family medicine and primary care, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Background: Number of reports linked Telogen effluvium to coronavirus disease 2019 (COVID-19) infection. However, data about Telogen effluvium after COVID-19 vaccination are limited. Objectives: To estimate prevalence of Telogen effluvium among those who received COVID-19 vaccination. Methods: A cross-sectional study was performed during July 2021. Adults who received one of recognized COVID-19 vaccine irrespective of previous COVID-19 infection were asked to fill a questionnaire. Results: The majority of participants were females (90.3%). The most common age group was between 21 and 30 years (51.9%). Out of 991 participants who were included in the current analysis, 670 (67.6%) reported post-vaccination hair fall. The probable causes of post-vaccination hair fall were vaccine-related in 185 (27.6%) participants, other causes in 326 (48.7%) participants, and unclear in 326 (48.7%) participants. Post-vaccination hair fall was significantly higher among females compared with males (68.5% versus 57.9%, Conclusion: We are reporting a high prevalence of post-vaccination hair fall, which affected approximately two-thirds of participants who received COVID-19 vaccines. Only 28% of these participants were apparently vaccine related. The role of COVID-19 infection and stress caused by infection and vaccine cannot be excluded. Primary care physician and dermatologist need to consider the possibility of COVID-19 vaccine as a potential cause of hair loss.
