Development of Novel Patient-Reported Outcome (PRO) and Observer-Reported Outcome (ObsRO) Instruments in Retinitis Pigmentosa (RP) and Leber Congenital Amaurosis (LCA): ViSIO-PRO and ViSIO-ObsRO.
Article in Ophthalmology and therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionRetinitis pigmentosa (RP) and Leber congenital amaurosis (LCA) are rare inherited retinal degenerative disorders resulting in visual impairments and impacts on patients' vision-dependent activities of daily living (ADL), mobility and distal health-related quality of life (HRQoL). This study aimed to conduct qualitative research to understand the patient experience of RP/LCA across genotypes and inform development of patient- and observer-reported outcome (PRO/ObsRO) instruments in RP/LCA.
methodsResearch activities included a qualitative literature review and review of existing visual function PRO instruments in RLBP1 RP, and concept elicitation (CE) and cognitive debriefing (CD) interviews of existing PRO instruments with patients with RLBP1 RP, expert clinicians, and payers. In wider RP/LCA, a social media listening (SML) study and a qualitative literature review was conducted, while psychometric evaluation of a PRO instrument in LCA was performed. Input from expert clinicians was sought at key stages.
resultsFindings from the qualitative literature reviews identified a range of visual function symptoms which had significant impacts on patients' vision-related ADL and distal HRQoL. Patient interviews identified additional visual function symptoms and impacts not previously reported in published literature. These sources informed development and refinement of a conceptual model displaying the patient experience of RP/LCA. Review of existing visual function PRO instruments, and CD interviews evaluating their content validity, confirmed that no existing instrument provides a comprehensive assessment of all concepts relevant to patients with RP/LCA. This highlighted the need for development of the Visual Symptom and Impact Outcomes PRO and ObsRO instruments to adequately assess the patient experience of RP/LCA.
conclusionsResults informed and supported development of the instruments to assess visual functioning symptoms and vision-dependent ADL, mobility and distal HRQoL in RP/LCA, in accordance with regulatory standards. Next steps to further support use in RP/LCA clinical trials/practice includes content and psychometric validation of the instruments in this population.
