Change in subjective well-being and the associated costs of a woman-targeted presbyopia correction programme among older craftswomen in Zanzibar: a cost-outcome and scenario analysis.

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
backgroundA pilot eyecare programme aimed to address the urgent eye health needs of older Zanzibari craftswomen. We investigated the impact of correcting presbyopia on their subjective well-being (SWB) 6 months post-correction and assessed the cost-effectiveness of a women-targeted presbyopia correction programme.
methodsThis study involved Zanzibari craftswomen aged 40 and older with presenting and corrected distance visual acuity better than 6/12 in both eyes and were presbyopic. Using a before-after method, we assessed SWB on a 10-point scale before and after providing free spectacles. Mean SWB scores and differences pre-correction and post-correction were calculated. Programme costs were analysed to determine the cost per SWB score gained and the monthly cost for each SWB score improvement. Additionally, scenario analysis estimated costs for 12 approaches.
resultsOf 282 craftswomen, 209 met the eligibility criteria. SWB scores significantly increased from 3.34 to 8.14 post correction (p<0.001). Screening costs totalled US$12 885.84, with an average cost of US$45.69 per craftswoman screened and US$61.66 per presbyopia identification. The total programme cost was US$14,574.69. One hundred fifty-four craftswomen experienced increased SWB, with a total of 747 score gains. Achieving one SWB score improvement cost an average of US$19.50, with a monthly average cost of US$3.40 per improvement. Utilising woman screeners, organised transport and ready-made spectacles appeared to be the most cost-effective approach.
conclusionCorrecting presbyopia through a targeted eyecare programme significantly enhanced SWB among craftswomen. While the programme seems cost-effective, further research is warranted to explore long-term economic benefits and definitively assess cost-effectiveness in larger studies.
