An age-matched comparative study of ocular biometry parameters in cataractous and non-cataractous eyes of children in Ibadan, Nigeria.

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
Objective: This study compared the preoperative ocular biometric parameters of children who had cataract with age-matched healthy children to provide an understanding of a range of typical measurements in indigenous African eyes and aid management of childhood cataract. Design: Observational, cross-sectional, comparative study of two groups- cases and controls. Setting: Child eye health tertiary health facility. Participants: Group A consisted of children aged 2 to 6 years with cataracts, and Group B of age-matched controls. Ocular biometry measurements including keratometry, axial length (AXL), pachymetry (central corneal thickness [CCT]) and tonometry were measured. Results: Thirty eyes of 24 children were studied in each group. Seventeen (70.8%) children had bilateral cataracts. The mean age of the cataract group (A) was 5.97±2.93 years, while that of the control group (B) was 6.33±2.89 years. The mean preoperative values for the ocular biometric parameters were: Group A AXL= 23.4(±1.4) mm versus Group B AXL= 22.7(±0.9) mm, p= 0.028; Group A CCT= 563.6(±59.7) µm versus Group B CCT= 551.0(±36.4) µm, p= 0.33; and Group A K = 43.4(±2.3) D versus Group B K = 42.5(±1.5) D, p= 0.08. Group A IOP was 13.7(±2.8) mmHg, while Group B IOP was 13.8 (±3.1) mmHg, p =0.93. Conclusion: There was no statistically significant difference in ocular biometric parameters between children's eyes with and without cataracts except for the axial length. Funding: None declared.
