Strengthening provider-initiated testing and counselling in Zimbabwe by deploying supplemental providers: a time series analysis.
Article in BMC health services research, 2019. 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
backgroundExpansion of provider-initiated testing and counselling (PITC) is one strategy to increase accessibility of HIV testing services. Insufficient human resources was identified as a primary barrier to increasing PITC coverage in Zimbabwe. We evaluated if deployment of supplemental PITC providers at public facilities in Zimbabwe was associated with increased numbers of individuals tested and diagnosed with HIV.
methodsFrom July 2016 to May 2017, International Training and Education Center for Health (I-TECH) deployed 138 PITC providers to supplement existing ministry healthcare workers offering PITC at 249 facilities. These supplemental providers were assigned to facilities on a weekly basis. Each week, I-TECH providers reported the number of HIV tests and positive diagnoses they performed. Using routine reporting systems, we obtained from each facility the number of clients tested and diagnosed with HIV per month. Including data both before and during the intervention period, and utilizing the weekly variability in placement locations of the supplemental PITC providers, we employed generalized estimating equations to assess if the placement of supplemental PITC providers at a facility was associated with a change in facility outputs.
resultsSupplemental PITC providers performed an average of 62 (SD = 52) HIV tests per week and diagnosed 4.4 (SD = 4.9) individuals with HIV per week. However, using facility reports from the same period, we found that each person-week of PITC provider deployment at a facility was associated with an additional 16.7 (95% CI, 12.2-21.1) individuals tested and an additional 0.9 (95% CI, 0.5-1.2) individuals diagnosed with HIV. We also found that staff placement at clinics was associated with a larger increase in HIV testing than staff placement at polyclinics or hospitals (24.0 vs. 9.8; p < 0.001).
conclusionsThis program resulted in increased numbers of individuals tested and diagnosed with HIV. The discrepancy between the average weekly HIV tests conducted by supplemental PITC providers (62) and the increase in facility-level HIV tests associated with one week of PITC provider deployment (16.7) suggests that supplemental PITC providers displaced existing staff who may have been reassigned to fulfil other duties at the facility.
