1 · What the graph read from 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.

2 · The registry

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

objectivesSARS-CoV-2 vaccination is a crucial intervention for infection control; however, the immune response to vaccination in dialysis patients has been reported to be moderate compared with healthy adults. There are few studies available on humoral response in immunised dialysis patients compared with well-matched control group, we conducted a prospective cohort study measuring SARS-CoV-2 antibody titres in Fukushima Prefecture, Japan since September 2021.

participantsWe compared the titres of both anti-SARS-CoV-2 S1 IgG and neutralising antibodies of 65 haemodialysis patients (dialysis group) with 500 residents in Soma, Fukushima (control group).

methodsCoarsened exact matching was used to balance sex, age and days from the second dose between dialysis and control groups.

resultsSignificant differences in the titres of anti-SARS-CoV-2 S1 IgG and neutralising antibodies were observed between the dialysis and control groups; anti-SARS-CoV-2 S1 IgG: 168.35 (4.48-1074.29) AU/mL and 269.81 (4.72-945.96) AU/mL in dialysis and control groups, p=0.02, neutralising antibodies: 35.77 (2.94-826.06) AU/mL and 62.22 (0.00-535.57) AU/mL, p=0.007, respectively).

conclusionsWe observed significantly reduced anti-SARS-CoV-2 S1 antibody and neutralising antibodies in haemodialysis patients compared with cohorts matched for duration after vaccination. Patients receiving haemodialysis should be carefully monitored for immunological responses to the vaccination and COVID-19 infection.
