An assessment of the effectiveness of an electronic wristband in improving routine immunization timeliness and reducing drop-out.
Article in Journal of public health (Oxford, England), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundTo assess the effectiveness of a wristband for immunization alert (WIA) as a reminder device to caregivers to improve immunization timeliness and reduce drop-outs.
methodsEight health facilities, selected from two local government areas in Kano state, Northwestern Nigeria, were clustered in a two-arm study involving an intervention group and a control group. Only the caregivers (757) from the intervention group received WIA as an immunization reminder device. Immunization timeliness data were then collected from the control and intervention groups for the period of intervention and analyzed using Microsoft Excel and IBM SPSS version 21.
resultsA cohort analysis of caregivers who received WIA at their second visit showed an increase in immunization timeliness from 10% at the second visit to 86% at the third visit and maintained at 66% for the fifth visit. A difference-in-difference analysis of the effect of WIA on immunization timeliness from baseline to end-line in the control and intervention groups showed a positive 30% increase in immunization timeliness associated with the introduction of WIA.
interpretationGiven that immunization timeliness and drop-outs are reported issues of concern in Northwestern Nigeria, the use of the WIA device is a recommended intervention.
